R-Studio free download Archives - sorry

David Zelený

Download the latest version from RStudio website; you will need Desktop version, Open Source Edition for your system; you may click here to get directly to the selection of actual RStudion version. Follow instructions for installation. If you already have RStudio installed in your computer, please check whether you have the latest version and update if you don't (in RStudio menu, go to Help > Check for Updates).

RStudio is a convenient software, which combines R program with text editor and graphical user interface (and offers much more, like organization of scripts and outputs into a projects within single folder, and for advanced users also convenient building of packages, document markup etc.). One thing I found a bit not handy is RStudio's native graphical output - it offers its own unique sizeable graphical output into one of the subpanels (usually the bottom-right one), but it sometimes produces troubles (especially in case when you draw more complex figures). The workaround is to open the original R drawing panel - just type into the console, and new active window will open (you can move it around the screen, or right-click on it by mouse and select “Stay on top” to keep it as the top window always visible on your screen).

Optionally, there is a number of other text editors, which can be associated with R, e.g. Tinn-R. You are free to use the editor of your choice. In the class, I will use RStudio.

Downloading R and RStudio

If you plan to use R, you will need to download R and install it on your computer. It is also advised that you download and install RStudio. RStudio will make it easier to use R and manage your R scripts. 

Two good things about R, are that it is free and it runs on most computers. 

You can download R from: https://www.r-project.org/ 

Figure 1 - R Project Main Page

What is CRAN and why is that a good thing? When you try to download R from the R Project website, you will have to pick a CRAN site to get your download of R. CRAN stands for the “Comprehensive R Archive Network” (CRAN), which is a collection of sites carrying identical material, consisting of the R distribution(s), the contributed extensions, documentation for R, and binaries. 

The CRAN master site is at WU (Wirtschaftsuniversität Wien) in Austria and is mirrored daily to many other CRAN sites around the world. Please use the CRAN site closest to you to reduce network load. 

From CRAN, you can obtain the latest official release of R, daily snapshots of R (copies of the current source trees), as gzipped and bzipped tar files, a wealth of additional contributed code, as well as pre-built binaries for various operating systems (Linux, Mac OS Classic, OS X, and MS Windows). CRAN also provides access to documentation on R, existing mailing lists and the R Bug Tracking system. 

Downloading R You can download R from: https://www.r-project.org/. Simply click on the CRAN link under Download in the list on the left side of the main R site. You can then pick from the list of worldwide CRAN sites for your download. There is a CRAN server at Washington University, St. Louis, MO, USA. That would be a good option. Clicking on the cran.wustl.edu link will take you to the actual download page.

Figure 3 - Washington University Saint Louis CRAN Mirror

The simplest option is to download the pre-compiled binary distribution for your operating system. Links for those are at the top of the Downloads page.

Figure 4 - R Downloads Page


Clicking the link on the downloads page will take you to the file repository. If you are trying to download R for OSX, the page will look like this.

Figure 5 - R OSX Downloads Page

You can either select the most recent version of R [arrow A] or download the version with the latest date [arrow B]. Select the download and save it to your Downloads folder. That is it. You are ready to install R on your computer.

If you are trying to download R for Windows, the page will look like this.

Figure 6 - R File Download Folders for Windows

You only need the base install of R. When you click the link for the base folder the next page will look like this: 

Figure 7 - R Download Files for Windows

Select the most recent version of R [arrow A]. This will be the version with the latest date of posting. If you have questions, you can read the version notes [arrow B]. Select the download and save it to your Downloads folder. That is it. You are ready to install R on your computer.

Downloading RStudio You can use R as it was installed on your computer but that involves entering commands from the Terminal prompt and editing R scripts in a separate text editor. RStudio is an easier option and it provides a useful set of tools that will make your work easier. 

You can download RStudio from https://www.rstudio.com/. Click the Download RStudio button near the top of the page. You will want to download the Open Source Edition of RStudio Desktop. This is the free version of the application. Commercial entities must pay for an RStudio license. As a student, you do not.

Figure 8 - RStudio Main Page

Click the Download RStudio link at the bottom of the page [red arrow] and then click the installer for your operating system. Save the RStudio installer download to the Downloads folder on your computer. Be sure to select the RStudio Desktop Open Source License version. You are ready to install RStudio on your computer.

Installing R and RStudio

R and RStudio are both free, open-source software, available for all commonly used operating systems. R is developed cooperatively and noncommercially under the auspices of the Free Software Foundation; RStudio is a commercial product.

R and RStudio install in the standard manner on each of Windows, macOS, and Linux systems. System-specific instructions for installing R are given below. Regardless of your operating system, you should install R before installing RStudio.

Please read and follow these instructions carefully. Installation assistance will also be availabile from the instructor (John Fox) and teaching assistant (Allison Leanage) prior to the start of the lecture series and during office hours.

Installing R on Windows

bulletVisit the Comprehensive R Archive Network (CRAN) and select a mirror site; a list of CRAN mirrors appears at the upper left of the CRAN home page. I suggest that you use the 0-Cloud mirror, which is the first on the list. Click on the link Download R for Windows, which appears near the top of the page; then click on install R for the first time, and subsequently on Download R x.y.z for Windows (where x.y.z is the current version of R, which is R 4.1.0 at the start of the lectures series). Once it is downloaded, double-click on the R installer. You may take all of the defaults, but I suggest that you make the following modifications:

bulletInstead of installing R in the standard location, C:\Program Files\R\R-x.y.z, I suggest that you use C:\R\R-x.y.z. Again, x.y.z is the current version of R. This will allow you to install packages in the main R library without running R with administrator privileges and may avoid problems that sometimes occur when there are spaces in paths.

bulletYou may take all of the remaining defaults in the R for Windows installer.

Building Packages Under Windows, etc. (Optional)

bulletIf you wish to build packages, or use compiled C, C++, or Fortran code in R, or use the rstan package for Bayesian inference, you will have to install some additional software and properly configure your Windows system. You do not have to be able to build R packages in order to install pre-built Windows binary packages from CRAN, so these steps are generally unnecessary unless you plan to write your own packages, use compiled code, or use rstan.None of these topics are covered in the lecture series.

bulletClick on the Rtools link on the R for Windows CRAN page. Download the current version of the Rtools installer and run it. You may take all of the other defaults. An additional necessary step is to add the Rtools usr\bin subdirectory to your system path; for example, if Rtools is installed in c:\rtoolsxy (which is the standard location for version xy of Rtools), then you would add c:\rtoolsxy\usr\bin; to your system path. Type this location carefully, including the terminating semicolon -- you don't want to mess up your path.

An alternative, and possibly safer, procedure for specifying the path to Rtools is described on the Rtools webpage.

If you want to be able to build R packages outside of RStudio, also add c:\R\R-x.y.z\bin; to the path (assuming that you installed R in the location that I suggested).

bulletIf you want to be able to build PDF help files for packages, download and install the MiKTeX LaTeX system; there is also a link to MiKTeX on the Building R for Windows page. Installing MiKTeX will also allow you to create Sweave and knitr LaTeX documents in RStudio, and to compile R Markdown documents directly to PDF files.

Installing R on macOS

bulletVisit the Comprehensive R Archive Network (CRAN) and select a mirror site; a list of CRAN mirrors appears at the upper left of the CRAN home page. I suggest that you use the 0-Cloud mirror, which is the first on the list. Click on the link Download R for MacOS X, which appears near the top of the page; then click on R-x.y.z.pkg (where x.y.z is the current version of R -- R 4.1.0 at the start of the lectures series), which assumes that you are using macOS 10.11 (El Capitan) or higher. You'll also find older versions of R if you have an older version of macOS. Note: As a general matter, you're probably better off updating your macOS to the current version.

bulletTwo macOS installers are provided for the current version of R: one for Macs that use Intel chips and one for newer Macs that use the Apple M1 chip. The former installer is named R-x.y.z.pkg and the latter is namedR-x.y.z-arm64.pkg. At present, I recommend that you use the R-x.y.z.pkg installer whether or not you have a Mac with an Intel chip. The Intel version will work with both kinds of Macs, and there are still some compatibility issues for certain packages associated with the M1-specific version of R.

bulletOnce it is downloaded, double-click on the R installer. You may take all of the defaults.

Building Packages Under macOS, etc. (Optional)

bulletIf you wish to build packages, or use compiled C, C++, or Fortran code in R, or use the rstan package for Bayesian inference, you must install the Apple Xcode developer tools. None of these topics is covered in the lecture series. For macOS 10.7 (Lion) or higher, you can install Xcode for free from the App Store. For earlier versions of macOS, Xcode can be installed from your system DVD or downloaded from the Apple developer website. You do not need Xcode to install pre-built macOS binary packages from CRAN, so this step is unnecessary unless you plan to write your own packages, use compiled code, or use the rstan Bayesian estimation package.

bulletSome R packages include Fortran, C, or C++ code; to build such packages, you will have to install compilers for these languages.The C and C++ compilers are included in the Apple Xcode tools, but you will have to separately download and install a Fortran compiler.

bulletIf you want to be able to build PDF help files, download and install the MacTeX LaTeX system. Installing MacTeX will also allow you to create Sweave and knitr LaTeX documents in RStudio, and to compile R Markdown documents directly to PDF files.

Installing X-Windows on macOS (Optional)

bulletSome R software (e.g., my Rcmdr package) makes use of the Tcl/Tk graphical-user-interface (GUI) builder via the tcltk package to create point-and-click interfaces and to display GUI elements such as progress bars. To use the tcltk package, which is a standard part of the R distribution, you must have the X11 windowing system installed on your Mac. Some other packages that don't use Tcl/Tk, such as the rgl package for dynamic 3D graphics, also require X11.

bulletCheck to see whether the X11 windowing system (X Windows) has already been installed on your computer. If you wish, it should do no harm to skip this step and simply go to the next step to install XQuartz.

For OS X 10.6 and 10.7, the file X11.app should appear in the Utilities folder under Applications in the finder. This application should always be installed under OS X 10.7.

For OS X 10.8 or higher, the file is named XQuartz.app and is no longer included with the operating system. XQuartz.app may also be installed in OS X 10.6 or 10.7.

Note that if you upgrade macOS, you will have to reinstall XQuartz even if you installed it previously.

You may also issue the command capabilities("X11") at the R command prompt. If the response is TRUE then X11 is installed.

bulletIf neither X11.app nor XQuartz.app is installed, install XQuartz from https://www.xquartz.org/. As mentioned, it should do no harm to install XQuartz even if you have X11 currently installed.

      1. Download the disk image (dmg) file for XQuartz.

      2. When you open this file by double-clicking on it, you'll find XQuartz.pkg; double-click on it to run the installer, clicking through all the defaults.

      3. Important: After the installer runs, you'll have to log out and back on to your macOS account, or just reboot your Mac. Also, on first use, XQuartz builds a cache of fonts and so initial performance may be slow; this problem should go away after a short period of time.

Installing R on Linux Systems

bulletVisit the Comprehensive R Archive Network (CRAN) and select a mirror site near you; a list of CRAN mirrors appears at the upper left of the CRAN home page. I suggest that you use the 0-Cloud mirror, which is the first on the list. Click on the link Download R for Linux, which appears near the top of the page. R is available for several Linux distributions (Debian, RedHat, SUSE, and Ubuntu); select your distribution, and proceed as directed.

bulletIf you have a Linux or Unix system that's not compatible with one of these distributions, you will have to compile R from source code; the procedure for doing so is described in the R FAQ (frequently asked questions) list.

Installing RStudio

bulletGo to the RStudio download page, select the free version of RStudio Desktop, click the Download button, and click on the link to the appropriate installer for your operating system (Windows, macOS, or Linux distro). Visit the RStudio IDE home page for more information about RStudio.

bulletOnce it is downloaded, run the RStudio installer and take all of the defaults: In Windows, double-click on the RStudio installer to start the installation; in macOS, double-click on the downloaded RStudio disk-image file, and drag the RStudio icon to the Applications folder.

bulletWhen you first run RStudio, it should detect your R installation and start the R console. To configure RStudio to your taste, select Tools > Global Options (Windows) or RStudio > Preferences (macOS) from the RStudio menus. In particular, I suggest that on the General options screen you deselectRestore .RData into workspace at startup, and set Save workspace to .RData on exit to Never.

bulletIf you encounter difficulties, consult the RStudio troubleshooting guide. or seek help from John or Allison.

Installing R Packages for the Lecture Series

bulletOnce you have installed R and RStudio, you can install additional packages required for the lecture series by typing the following command at the > command prompt in the R Console (and pressing the Enter or return key):

install.packages(c("car", "data.table", "effects", "knitr", "lme4", "rgl", "rmarkdown", "sfsmisc", "tidyverse"))

You can simply copy and paste this command from these installation instructions. Alternatively, you can install packages from the RStudio Packages tab. Be aware that, depending on the speed of your internet connection, it may take some time to download and install these packages and their dependencies.

bulletIf you want to try using C++ code within R (not discussed in the lecture series), also install the Rcpp package, install.packages("Rcpp"). You'll also have to install a C++ compiler, as described in the sections above on building packages under Windows and macOS.

bullet Similarly, if you want to use the Stan Bayesian statistical software via the rstan package (not discussed in the lecture series), you'll have to install the package by the command install.packages("rstan"), and also install a C++ compiler.

When important files disappear from your computer, your first instinct may be to take immediate, frantic action. While it is important to act quickly, doing so without taking the proper steps can actually worsen your chances of recovering your data. So, before you do anything else, take some time to read these tips.

First and foremost, don't panic. Take some relief in the fact that there's a very good chance that your files are still intact and can be easily recovered. If, that is, you go about it properly. That's because when you delete a file (e.g. by emptying it from the Recycle Bin or Trash Bin), it isn't eliminated right away. Instead, the file system simply flags the disk space as available for use by another program. So, if no other program has used that space yet, then 100% of your file is still there. The same is true even if you repartition or format a disk or drive.

The key is to avoid any read/write activity on the disk at all costs. Surfing the web, downloading programs, installing them and rebooting your machine are all very read/write intensive activities. For this reason, scouring the web for file undelete programs and trying them until you find one that works is about the worst thing you can do. It's entirely possible that the data recovery software you download will actually overwrite the file you are trying to salvage.

You can do a couple of things to prevent this from happening. If the data you are trying to recover is on a removable disk, such as flash card or USB drive, disconnect it for now. If the file you deleted was on your system disk (usually C:\) or an internal hard drive, stop using that computer. Use another machine to download and install a program such as R-Undelete or R-Studio. If you have the technical know-how, go ahead and remove the internal disk from the computer and attach it to a computer running your file recovery tool. Do not install your file recovery software to the same disk that you are trying to recover from. If you cannot remove the drive from the computer, then try using a portable version of R-Studio or R-Undelete installed on removable media.

If your data is lost because the hard drive is failing or being attacked by a virus, then you may want to create an image of the disk. This is a good tactic because it essentially "freezes" the disk in time, preventing any further loss of data. You can then perform your file recovery on the disk image, rather than the disk itself, which may be undergoing further damage as time goes on. Oftentimes, the very act of data recovery can cause further damage to a disk, particularly when the drive is physically damaged. A disk image stops this from happening. Disk images are also useful for complex recovery tasks, such as RAID recovery.

In summary, when you lose a file, make sure you do the following:

  1. Don't panic.
  2. Stop using the disk immediately.
  3. Install data recovery software to another disk or computer.
  4. Create a disk image for advanced recovery or heavily damaged disks.

How to install EZR on Windows
There are two methods to install EZR on Windows. The first one is easier, but the version of R and R commander is fixed. The second one is a little bit complicated but it enables installation of EZR on the latest version of R and R commander. However, I recommend the easier method, because EZR may casue an unexpected error according to an update of a package that EZR depends on.

1. Easier method.
Download the following file (EZRsetupENG.exe). EZR is installed along with R and R commander just by running this installer on Windows XP, VISTA, 7, 8 or 10 (both 32- and 64-bit versions).

Installing R and RStudio

To get started with R, you need to acquire your own copy. This appendix will show you how to download R as well as RStudio, a software application that makes R easier to use. You’ll go from downloading R to opening your first R session.

Both R and RStudio are free and easy to download.

How to Download and Install R

R is maintained by an international team of developers who make the language available through the web page of The Comprehensive R Archive Network. The top of the web page provides three links for downloading R. Follow the link that describes your operating system: Windows, Mac, or Linux.

Windows

To install R on Windows, click the “Download R for Windows” link. Then click the “base” link. Next, click the first link at the top of the new page. This link should say something like “Download R 3.0.3 for Windows,” except the 3.0.3 will be replaced by the most current version of R, R-Studio free download Archives. The link downloads an installer program, which installs the most up-to-date version of R for Windows. Run this program and step through the installation wizard that appears. The wizard will install R into your program R-Studio free download Archives folders and place a shortcut in your Start menu. Note that you’ll need to have all of the appropriate administration privileges to install new software on your machine.

Mac

To install R on a Mac, click the “Download R for Mac” link. Next, click on the package link (or the package link for the most current release of R). An installer will download to guide you through the installation process, which is very easy. The installer lets you customize your installation, but the defaults will be suitable for most users. I’ve never found a reason to change them. If your computer requires a password before installing new progams, you’ll need it here.

Binaries Versus Source

R can be installed from precompiled binaries or built from source on any operating system. For Windows and Mac machines, installing R from binaries is extremely easy. The binary comes preloaded in its own installer. Although you can build R from source on these platforms, the process is much more complicated and won’t provide much benefit for most users. For Linux systems, the opposite is true. Precompiled binaries can be found for some systems, but it is much more common to build R from source files when installing on Linux. The download pages on CRAN’s websiteprovide information about building R from source for the Windows, Mac, and Linux platforms.

Linux

R comes preinstalled on many Linux systems, but you’ll want the newest version of R if yours is out of date. The CRAN website provides files to build R from source on Debian, Redhat, SUSE, and Ubuntu systems under the link “Download R for Linux.” Click the link and then follow the directory trail to the version of Linux you wish to install on, R-Studio free download Archives. The exact installation procedure will vary depending on the Linux system you use. CRAN guides the process by grouping each set of source files with documentation or README files that explain how to install on your system.

32-bit Versus 64-bit

R comes in both 32-bit and 64-bit versions. Which should you use? In most cases, it won’t matter. Both versions use 32-bit integers, which means they compute numbers to the same numerical precision. The difference occurs in the way each version manages memory. 64-bit R uses 64-bit memory pointers, and 32-bit R uses 32-bit memory pointers. This means 64-bit R has a larger memory space to use (and search through).

As a rule of thumb, 32-bit builds of R are faster than 64-bit builds, though not always. On the other hand, 64-bit builds can handle larger files and data sets with fewer memory management problems. In either version, the maximum allowable vector size tops out at around 2 billion elements. If your operating system doesn’t support 64-bit programs, or your RAM is less than 4 GB, 32-bit R is for you. The Windows and Mac installers will automatically install both versions if your system supports 64-bit R.

Using R

R isn’t a program that you can open and start using, like Microsoft Word or Internet Explorer. Instead, R is a computer language, like C, C++, or UNIX. You use R by writing commands in the R language and asking your computer to interpret them. In the old days, people ran R code in a UNIX terminal window—as if they were hackers in a movie from the 1980s. Now almost everyone uses R R-Studio free download Archives an application called RStudio, and I recommend that you do, too.

R and UNIX

You can still run R in a UNIX or BASH window by typing the command:

which opens an R interpreter. You can then do your work and close the interpreter by running when you are finished, R-Studio free download Archives.

RStudio

RStudio is an application like Microsoft Word—except that instead of helping you write in English, RStudio helps you write in R. I use RStudio throughout the book because it makes using R much easier. Also, the RStudio interface looks the same for Windows, Mac OS, and Linux. That will help me match the book to your personal experience.

You can download RStudio for free. Just click the “Download RStudio” button and follow the simple instructions that follow. Once you’ve installed RStudio, you can open it like any other program on your computer—usually by clicking an icon on your desktop.

The R GUIs

Windows and Mac users usually do not program from a terminal window, so the Windows and Mac downloads for R come R-Studio free download Archives a simple program that opens a terminal-like window for you to run R code in. This is what opens when you click the R icon on your Windows or Mac computer. These programs do a little more than the basic terminal window, but not much. You may hear people refer to them as the Windows or Mac R GUIs.

When you open RStudio, a window appears with three panes in it, as in Figure A.1. The largest pane is a console window. This is where you’ll run your R code and see results. The console window is exactly what you’d see if you ran R from a UNIX console or the Windows or Mac GUIs. Everything else you see is unique to RStudio. Hidden in the other panes are a text editor, a graphics window, a debugger, a file manager, and much more. You’ll learn about these panes as they become useful throughout the course of this book.

The RStudio IDE for R.

Figure A.1: The RStudio IDE for R.

Do I still need to download R?

Even if you use RStudio, you’ll still need to download R to your computer. RStudio helps you use the version of R that lives on your computer, but it doesn’t come with a version of R visual studio crack Archives its own.

Opening R

Now that you have both R and RStudio on your computer, you can begin using R by opening the RStudio program. Open RStudio just as you would any program, by clicking on its icon or by typing “RStudio” at the Windows Run prompt.

David Zelený

Download the latest version from RStudio website; you will need Desktop version, Open Source Edition for your system; you may click here to get directly to the selection of actual RStudion version. Follow instructions for installation. If you already have RStudio installed in your computer, please check whether you have the latest version and update if you don't (in RStudio menu, go to Help > Check for Updates).

RStudio is a convenient software, R-Studio free download Archives, which combines R program with text editor and graphical user interface (and offers much more, like organization of scripts and outputs into a projects within single folder, and for advanced users also convenient building of packages, document markup etc.). One thing I found a bit not handy is RStudio's native graphical output - it offers its own unique sizeable graphical output into one of the subpanels (usually the bottom-right one), but it sometimes produces troubles (especially in case when you draw more complex figures). The workaround is to open the original R drawing panel - just type into the console, and new active window will open (you can move it around the screen, or right-click on it by mouse and select “Stay on top” to keep it as the top window always visible on your screen).

Optionally, there is a number of other text editors, which can be associated with R, e.g. Tinn-R. You are free to use the editor of your R-Studio free download Archives. In the class, I will use RStudio.

Installing R and RStudio

R and RStudio are both free, open-source software, available for all commonly used operating systems, R-Studio free download Archives. R is developed cooperatively and noncommercially under the auspices of the Free Software Foundation; RStudio is a commercial product.

R and RStudio install in the standard manner on each of Windows, macOS, and Linux systems. System-specific instructions for installing R are given below. Regardless of your operating system, you should install R before installing RStudio.

Please read and follow these instructions carefully, R-Studio free download Archives. Installation assistance R-Studio free download Archives also be availabile from the instructor (John Fox) and teaching assistant (Allison Leanage) prior to the start of the lecture series and during office hours.

Installing R on Windows

bulletVisit the Comprehensive R Archive Network (CRAN) and select a mirror site; a list of CRAN mirrors appears at the upper left of the CRAN home page. I suggest that you use the 0-Cloud mirror, which is the first on the list. Click on the link Download R for Windows, which appears near the top of the R-Studio free download Archives then click on install R for the first time, and subsequently on Download R x.y.z for Windows (where x.y.z is the current version of R, which is R 4.1.0 at the start of the lectures series). Once it is downloaded, double-click on the R installer. You may take all of the defaults, but I suggest that you make the following modifications:

bulletInstead of installing R in the standard location, R-Studio free download Archives Files\R\R-x.y.z, I suggest that you use C:\R\R-x.y.z. Again, x.y.z is the current version of R. This will allow you to install packages in the main R library without running R with administrator privileges and may Arquivos Quadrinhos problems that sometimes occur when there are spaces in paths.

bulletYou may take all of the remaining defaults in the R for Windows installer.

Building Packages Under Windows, etc. (Optional)

bulletIf you wish to build packages, R-Studio free download Archives, or use R-Studio free download Archives C, C++, or Fortran code in R, or use the rstan package for Bayesian inference, you will have to install some additional software and properly configure your Windows system. You do not have to be able to build R packages in order to install pre-built Windows binary packages from CRAN, so these steps are generally unnecessary unless you plan to write your own packages, use compiled code, or use rstan.None of these topics are covered in the lecture series.

bulletClick on the Rtools link on the R for Windows CRAN page. Download the current version of the Rtools installer and run it, R-Studio free download Archives. You may take all of the other defaults. An additional necessary step is to add the Rtools usr\bin subdirectory to your system path; for example, if Rtools is installed in c:\rtoolsxy (which is the standard location for version xy of Rtools), then you would add c:\rtoolsxy\usr\bin; to your system path. Type this location carefully, including the terminating semicolon -- you don't want to mess up your path.

An alternative, and possibly safer, procedure for specifying the path to Rtools is described on the Rtools webpage.

If you want to be able to build R packages outside of RStudio, also add c:\R\R-x.y.z\bin; to the path (assuming that you installed R in the location that I suggested).

bulletIf you want to be able to build PDF help files for packages, download and install the MiKTeX LaTeX system; there is also a link to MiKTeX on the Building R for Windows page. Installing MiKTeX will also allow you to create Sweave and knitr LaTeX documents in RStudio, and to compile R Markdown documents directly to PDF files.

Installing R on macOS

bulletVisit the Comprehensive R Archive Network (CRAN) and select a mirror site; a list of CRAN mirrors appears at the upper left of the CRAN home page. I suggest that you use the 0-Cloud mirror, R-Studio free download Archives, which is the first on the list. Click on the link Download R for MacOS X, which appears near the top of the page; then click on R-x.y.z.pkg (where x.y.z is the current version of R -- R 4.1.0 at the start of the lectures series), which assumes that you are using macOS 10.11 (El Capitan) or higher. You'll also find older R-Studio free download Archives of R if you have an older version of macOS. Note: As a general matter, you're probably better off updating your macOS to the current version.

bulletTwo macOS installers are provided for the current version of R: one for Macs that use Intel chips and one for newer Macs that use the Apple M1 chip. The former installer is named R-x.y.z.pkg and the latter is namedR-x.y.z-arm64.pkg, R-Studio free download Archives. At present, I recommend that you use the R-x.y.z.pkg installer whether or not you have a Mac with an Intel chip. The Intel version will work with both kinds of R-Studio free download Archives, and there are still some compatibility issues for certain packages associated with the M1-specific version of R.

bulletOnce it is downloaded, double-click on the R installer. You may take all of the defaults.

Building Packages Under macOS, etc. (Optional)

bulletIf you wish to build packages, or use compiled C, C++, or Fortran code in R, or use the rstan package for Bayesian inference, you must install the Apple Xcode developer tools. None of these topics is covered in the lecture series. For macOS 10.7 (Lion) or higher, you can install Xcode for free from the App Store. For earlier versions of macOS, Xcode can be installed from your system DVD or downloaded from the Apple developer website. You do not need Xcode to install pre-built R-Studio free download Archives binary packages from CRAN, so this step is unnecessary unless you plan to write your own packages, use compiled code, or use the rstan Bayesian estimation package.

bulletSome R packages include Fortran, C, or C++ code; to build such packages, you will have to install compilers for these languages.The C and C++ compilers are included in the Apple Xcode tools, but you will have to separately download and install a Fortran compiler.

bulletIf you want to be able to build PDF help files, download and install the MacTeX LaTeX system. Installing MacTeX will also allow you to create Sweave and knitr LaTeX documents in RStudio, R-Studio free download Archives, and to compile R Markdown documents directly to PDF files.

Installing X-Windows on macOS (Optional)

bulletSome R software (e.g., my Rcmdr package) makes use of the Tcl/Tk graphical-user-interface (GUI) builder via the tcltk package to create point-and-click interfaces and to display GUI elements such as progress bars. To use the tcltk package, which is a standard part of the R distribution, you must have the X11 windowing system installed on your Mac. Some other packages that don't use Tcl/Tk, such as the rgl package for dynamic 3D graphics, also require X11.

bulletCheck to see whether the X11 windowing system (X Windows) has already been installed on your computer, R-Studio free download Archives. If you wish, R-Studio free download Archives, it should do no harm to skip this step and simply go to the next step to install XQuartz.

For OS X 10.6 and 10.7, the file X11.app should appear in the Utilities folder under Applications in the finder. This application should always be installed under OS X 10.7.

For OS X 10.8 or higher, the file is named XQuartz.app and is no longer included with the operating system. XQuartz.app may also be installed in OS X 10.6 or 10.7.

Note that if you upgrade macOS, you will have to reinstall XQuartz even if you installed it previously.

You may also issue the command capabilities("X11") at the R command prompt. If the response is TRUE then X11 is installed.

bulletIf neither X11.app nor XQuartz.app is installed, install XQuartz from https://www.xquartz.org/. As mentioned, it should do no harm to install XQuartz even if you have X11 currently installed.

      1. Download the disk image (dmg) file for XQuartz.

      2. When you open this file by double-clicking on it, you'll find XQuartz.pkg; double-click on it to run the installer, R-Studio free download Archives, clicking through all the defaults.

      3. Important: After the installer runs, you'll have to log out and back on to your macOS account, or just reboot your Mac. Also, on first use, XQuartz builds a cache of fonts and so initial performance may be slow; this problem should go away after a short period of time.

Installing R on Linux Systems

bulletVisit the Comprehensive R Archive Network (CRAN) and select a mirror site near you; a list of CRAN mirrors appears at the upper left of the CRAN home page. I suggest that you use the 0-Cloud mirror, which is the first on the list. Click on the link Download R for Linux, R-Studio free download Archives, which appears near the top of the page. R is available for several Linux distributions (Debian, RedHat, SUSE, and Ubuntu); select your distribution, and proceed as directed.

bulletIf you have a Linux or Unix system that's not compatible with one of these distributions, you will have to compile R from source code; the procedure for doing so is described in the R FAQ (frequently asked questions) list.

Installing RStudio

bulletGo to the RStudio download page, select the free version of RStudio Desktop, click the Download button, R-Studio free download Archives, and click on the link to the appropriate installer for your operating system (Windows, macOS, or Linux distro). Visit the RStudio IDE home page for more information about RStudio.

bulletOnce it is downloaded, run the RStudio installer and take all of the defaults: In Windows, double-click on the RStudio installer to start the installation; in macOS, double-click on the downloaded RStudio disk-image file, R-Studio free download Archives, and drag the RStudio icon to R-Studio free download Archives Applications folder.

bulletWhen you first R-Studio free download Archives RStudio, it should detect your R installation and start the R console. To configure RStudio to your taste, select Tools > Global Options (Windows) or RStudio > Preferences (macOS) from the RStudio menus. In particular, I suggest that on the General options screen you deselectRestore .RData into workspace at startup, and set Save workspace to .RData on exit to Never.

bulletIf you encounter difficulties, consult the RStudio troubleshooting guide. or seek help from John or Allison.

Installing R Packages for the Lecture Series

bulletOnce you have installed R and RStudio, you can install additional packages required for the lecture series by typing the following command at the > command prompt in the R Console (and pressing the Enter or return key):

install.packages(c("car", "data.table", "effects", "knitr", "lme4", "rgl", "rmarkdown", "sfsmisc", "tidyverse"))

You can simply copy and paste this command from these installation instructions. Alternatively, you can install packages from the RStudio Packages tab. Be aware that, depending on the speed of your internet connection, it may take some time to download and install these packages and their dependencies.

bulletIf you want to try using C++ code within R (not discussed in the lecture series), also install the Rcpp package, install.packages("Rcpp"). You'll also have to install a C++ compiler, R-Studio free download Archives described in the sections above on building packages under Windows and macOS.

bullet Similarly, if you want to use the Stan Bayesian statistical software via the rstan package (not R-Studio free download Archives in the lecture series), you'll have to install the package by the command install.packages("rstan"), and also install a C++ compiler.

Cons:
  • Comprehensive but complex user interface. There is a learning curve for beginners.
  • Slightly confusing pricing structure for Windows.

Main Recovery Features in R-Studio

The hex editor inside <b>R-Studio free download Archives</b> width=

R-Studio comes jam-packed with many useful features. So many, in fact, R-Studio free download Archives, that a basic user may struggle to understand what most of them do. However, having a wide selection of features to use opens up a lot of functionality from a single application.

  • RAID Recovery – If part of your RAID (0/1/4/5/6/1+0) has broken down, you can create a virtual RAID within R-Studio to access and recover your data before attempting to fix it.
  • Network Recovery – You can recover data from computers that are connected to the network and running a compatible operating system. Not only that, but the recovered data can be stored to the guest computer or any network location that it’s connected to.
  • Disk Imaging – Create an image file of your entire hard drive or partition. This allows you to perform recovery on an image of the drive rather than the actual drive to prevent any further loss of data.
  • S.M.A.R.T. Monitoring – R-Studio monitors your drive’s S.M.A.R.T. R-Studio free download Archives, Analysis and Reporting Technology) data and alerts you to any potential failures that may occur. This gives the opportunity to make copies of your data if you drive is starting to fail.
  • Hex Editor – For confident users with a technical understanding of how data is stored, you can edit data directly using the built-in hex editor.
  • Filter/Mask – Use a mask to quickly search for files according to their file extensions. If you want to recover all files of that type, use a filter to automatically mark them all for recovery.

Suffice to say, R-Studio free download Archives, R-Studio is a complete recovery solution that equips R-Studio free download Archives with everything you need to recover data, plus more.

How to Recover Data Using R-Studio

Now that we know what R-Studio brings to the table, how does it actually perform? While all of those additional features and tools are useful for other tasks, R-Studio file recovery is the focus. I’ve tested the software in a real-world data recovery scenario to see how it holds up.

In this test, I’ve deliberately deleted three text documents containing lorem ipsum from my Documents folder and three image files from my Pictures folder. I also deleted them permanently from the Recycle Bin.

The latest version of R-Studio is 8.16 (build 180499) was released on March 24, 2021. The free version allows you to recover files that are 256KB or below. Anything above will require a paid license.

  1. Download R-Studio and open the install file.Downloading R-Studio
  2. Click Next and follow the on-screen instructions to complete the installation. Open it when finished.Installing R-Studio
  3. Select the drive or partition that contains the lost or deleted R-Studio free download Archives. Click Scan.Scanning the drive in R-Studio
  4. Click Scan. If you’re a technical user and prefer to customize the scan parameters, this is where you can modify what part of the drive is scanned.Starting the R-Studio scan
  5. Click Show Files.Showing what files R-Studio discovered
  6. Use the Find/Mark function to automatically find and mark files for recovery based on their file type.Filtering the results
  7. When ready, click Recover Marked.Recovering the marked files
  8. Specify the output location, R-Studio free download Archives. Click Ok.Finalizing the recovery from R-Studio

At the end of it, R-Studio didn’t allow me to recover any of the image files due to them all being above 256KB. However, using the Preview function, I was able to determine at least one image file was found. As for the text documents, R-Studio free download Archives, none of them were recovered. The closest discovery to recovering the text files was other text files that simply contained the old file names and directories of the text documents before they were deleted.

Interface and User Experience

The R-Studio interface

Downloading and installing R-Studio data recovery is super easy. The installation file is 63.95MB and the application takes up 932.8MB of space on your drive when it’s installed. During the installation, you’ll even receive a friendly notice that warns R-Studio free download Archives about the dangers of installing software on the same drive you want to recover data from, R-Studio free download Archives. A small but very nice touch for those who are unaware of the potential dangers associated with doing so.

The main interface of R-Studio is easily overwhelming the first time you see it. It favors showing the user as much technical information as possible, and as a result, it appears overcomplicated and challenging to navigate. For recovery experts, having this information readily available can make your life easier. For the average person who wants to recover a few documents, a lot of it is unnecessary.

I think R-Studio would benefit from offering two views: Basic or Advanced. Giving users the ability to ‘simplify’ the process will make it more appealing and easier to navigate and use.

Security and Privacy

R-Studio makes it very clear during their checkout process that the security of your personal information is of utmost importance. As you make payment, you’re protected by SSL encryption to protect your information from prying eyes. Alternatively, if you’d prefer not to pay for security reasons, you can pay using wire transfer, personal checks, bank drafts, or money orders.

Performing a scan using Windows Security yielded no concerns regarding this software. If you’re concerned about your digital safety, consider trialing the software in a virtual environment before attempting actual recovery to familiarize yourself with the software and assure yourself of its safety.

Pricing and Plans

The pricing structure for R-Studio is unconventional and comprehensive, R-Studio free download Archives, to the point where buying a license can be confusing, R-Studio free download Archives. You first need to decide what operating system R-Studio free download Archives want to buy a license for, then what sort of file systems you want to recover data from.

The R-Studio Technician license gives you full access to the software on all operating systems for $899. This plan is likely targeted towards businesses considering the price and the fact that it’s the only option that allows commercial use.

Windows Pricing

If you’re buying a Windows license, you’ll need to choose one of four plans, five if you include the Technician license. I’ve broken down each plan below, as well as what you’ll get with it. 

R-Studio NetworkR-StudioR-Studio NTFSR-Studio FAT

NTFS/ReFS
FAT/exFAT
Ext2/Ext3/Ext4/ ISO9660
HFS+/APFS/ HFS/UFS
UStar/Tar/ CPIO/Pax
Network recovery

On first impression, it seems R-Studio could simplify their pricing by removing the R-Studio NTFS and R-Studio FAT versions and just keep the standard R-Studio license. Most data recovery tools already support both NTFS and FAT file systems in their base versions, and by making this change, making a choice will be easier.

Mac and Linux Pricing

If you’re using Mac OS X or Linux, deciding is much easier. Each operating system has three licenses each to choose from when you include the Technician license. It seems they’ve dropped the NTFS and FAT versions for Mac and Linux, opting for a singular version that includes both.

You don’t get access to both Mac and Linux with a single license unless you get the Technician plan. Each operating system still requires its own license. We’ve just combined their pricing into a single table as the pricing is identical.

There’s little that it doesn’t include in terms of features, offering so much more than other recovery solutions on the market.

In my tests, it wasn’t able to recover the data I had deleted, which had me disappointed considering I was so impressed with what R-Studio has to offer. However, seeing as the demo version only allows you to recover files up to 256KB in R-Studio free download Archives, this prevented me from recovering all of the files I wanted to. Despite that, I was able to preview them, which may indicate they could be recovered with a paid license.

R-Studio is a heavyweight in the data recovery industry. It includes a vast array of useful tools and features that help recover data from even the most complex data-loss situations. But, how well can it recover the data that you’ve lost?

In this R-Studio review, I’ll take a close look at what R-Studio has to offer in terms of features, efficiency, pricing, and support. Read on if you’re interested to learn more about what this application can do for you.

ParameterValue
🚄 Recovery speed:Average to good. This will depend on the size of your drive.
💻 Supported platforms:Windows, Mac, and Linux.
💰 Pricing:Multiple licenses available from $49.99 to $899.
Support:Email or phone support. You can also use the FAQ page, knowledge base, or public forum.
Pros:
  • Lots of useful features, including RAID recovery, network recovery, disk imaging, and S.M.A.R.T. monitoring.
  • Competitive pricing for what you receive.
  • Use a filter to easily mark all discovered files according to parameters like file extension.
Cons:
  • Comprehensive but complex user interface. There is a learning curve for beginners.
  • Slightly confusing pricing structure for Windows.

Main Recovery Features in R-Studio

The hex editor inside R-Studio

R-Studio comes jam-packed with many useful features. So many, in fact, that a basic user may struggle to understand what most of them do. However, having a wide selection of features to use opens up a lot of functionality from a single application.

  • RAID Recovery – If part of your RAID (0/1/4/5/6/1+0) has broken down, you can create a virtual RAID within R-Studio to access and recover your data before attempting to fix it.
  • Network Recovery – You can recover data from computers that are connected to the network and running a compatible operating system. Not only that, but the recovered data can be stored to the guest computer or any network location that it’s connected to.
  • Disk Imaging – Create an image file of your entire hard drive or partition. This allows you to perform recovery on an image of the drive rather than the actual drive to prevent any further loss of data.
  • S.M.A.R.T. Monitoring – R-Studio monitors your drive’s S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) data and alerts you to any potential failures that may occur. This gives the opportunity to make copies of your data if you drive is starting to fail.
  • Hex Editor – For confident users with a technical understanding of how data is stored, you can edit data directly using the built-in hex editor.
  • Filter/Mask – Use a mask to quickly search for files according to their file extensions. If you want to recover all files of that type, use a filter to automatically mark them all for recovery.

Suffice to say, R-Studio is a complete recovery solution that equips you with everything you need to recover data, plus more.

How to Recover Data Using R-Studio

Now that we know what R-Studio brings to the table, how does it actually perform? While all of those additional features and tools are useful for other tasks, R-Studio file recovery is the focus. I’ve tested the software in a real-world data recovery scenario to see how it holds up.

In this test, I’ve deliberately deleted three text documents containing lorem ipsum from my Documents folder and three image files from my Pictures folder. I also deleted them permanently from the Recycle Bin.

The latest version of R-Studio is 8.16 (build 180499) was released on March 24, 2021. The free version allows you to recover files that are 256KB or below. Anything above will require a paid license.

  1. Download R-Studio and open the install file.Downloading R-Studio
  2. Click Next and follow the on-screen instructions to complete the installation. Open it when finished.Installing R-Studio
  3. Select the drive or partition that contains the lost or deleted files. Click Scan.Scanning the drive in R-Studio
  4. Click Scan. If you’re a technical user and prefer to customize the scan parameters, this is where you can modify what part of the drive is scanned.Starting the R-Studio scan
  5. Click Show Files.Showing what files R-Studio discovered
  6. Use the Find/Mark function to automatically find and mark files for recovery based on their file type.Filtering the results
  7. When ready, click Recover Marked.Recovering the marked files
  8. Specify the output location. Click Ok.Finalizing the recovery from R-Studio

At the end of it, R-Studio didn’t allow me to recover any of the image files due to them all being above 256KB. However, using the Preview function, I was able to determine at least one image file was found. As for the text documents, none of them were recovered. The closest discovery to recovering the text files was other text files that simply contained the old file names and directories of the text documents before they were deleted.

Interface and User Experience

The R-Studio interface

Downloading and installing R-Studio data recovery is super easy. The installation file is 63.95MB and the application takes up 932.8MB of space on your drive when it’s installed. During the installation, you’ll even receive a friendly notice that warns you about the dangers of installing software on the same drive you want to recover data from. A small but very nice touch for those who are unaware of the potential dangers associated with doing so.

The main interface of R-Studio is easily overwhelming the first time you see it. It favors showing the user as much technical information as possible, and as a result, it appears overcomplicated and challenging to navigate. For recovery experts, having this information readily available can make your life easier. For the average person who wants to recover a few documents, a lot of it is unnecessary.

I think R-Studio would benefit from offering two views: Basic or Advanced. Giving users the ability to ‘simplify’ the process will make it more appealing and easier to navigate and use.

Security and Privacy

R-Studio makes it very clear during their checkout process that the security of your personal information is of utmost importance. As you make payment, you’re protected by SSL encryption to protect your information from prying eyes. Alternatively, if you’d prefer not to pay for security reasons, you can pay using wire transfer, personal checks, bank drafts, or money orders.

Performing a scan using Windows Security yielded no concerns regarding this software. If you’re concerned about your digital safety, consider trialing the software in a virtual environment before attempting actual recovery to familiarize yourself with the software and assure yourself of its safety.

Pricing and Plans

The pricing structure for R-Studio is unconventional and comprehensive, to the point where buying a license can be confusing. You first need to decide what operating system you want to buy a license for, then what sort of file systems you want to recover data from.

The R-Studio Technician license gives you full access to the software on all operating systems for $899. This plan is likely targeted towards businesses considering the price and the fact that it’s the only option that allows commercial use.

If you’re buying a Windows license, you’ll need to choose one of four plans, five if you include the Technician license. I’ve broken down each plan below, as well as what you’ll get with it.

Installing R and RStudio

R and RStudio are both free, open-source software, available for all commonly used operating systems. R is developed cooperatively and noncommercially under the auspices of the Free Software Foundation; RStudio is a commercial product.

R and RStudio install in the standard manner on each of Windows, macOS, and Linux systems. System-specific instructions for installing R are given below. Regardless of your operating system, you should install R before installing RStudio.

Please read and follow these instructions carefully. Installation assistance will also be availabile from the instructor (John Fox) and teaching assistant (Allison Leanage) prior to the start of the lecture series and during office hours.

Installing R on Windows

bulletVisit the Comprehensive R Archive Network (CRAN) and select a mirror site; a list of CRAN mirrors appears at the upper left of the CRAN home page. I suggest that you use the 0-Cloud mirror, which is the first on the list. Click on the link Download R for Windows, which appears near the top of the page; then click on install R for the first time, and subsequently on Download R x.y.z for Windows (where x.y.z is the current version of R, which is R 4.1.0 at the start of the lectures series). Once it is downloaded, double-click on the R installer. You may take all of the defaults, but I suggest that you make the following modifications:

bulletInstead of installing R in the standard location, C:\Program Files\R\R-x.y.z, I suggest that you use C:\R\R-x.y.z. Again, x.y.z is the current version of R. This will allow you to install packages in the main R library without running R with administrator privileges and may avoid problems that sometimes occur when there are spaces in paths.

bulletYou may take all of the remaining defaults in the R for Windows installer.

Building Packages Under Windows, etc. (Optional)

bulletIf you wish to build packages, or use compiled C, C++, or Fortran code in R, or use the rstan package for Bayesian inference, you will have to install some additional software and properly configure your Windows system. You do not have to be able to build R packages in order to install pre-built Windows binary packages from CRAN, so these steps are generally unnecessary unless you plan to write your own packages, use compiled code, or use rstan.None of these topics are covered in the lecture series.

bulletClick on the Rtools link on the R for Windows CRAN page. Download the current version of the Rtools installer and run it. You may take all of the other defaults. An additional necessary step is to add the Rtools usr\bin subdirectory to your system path; for example, if Rtools is installed in c:\rtoolsxy (which is the standard location for version xy of Rtools), then you would add c:\rtoolsxy\usr\bin; to your system path. Type this location carefully, including the terminating semicolon -- you don't want to mess up your path.

An alternative, and possibly safer, procedure for specifying the path to Rtools is described on the Rtools webpage.

If you want to be able to build R packages outside of RStudio, also add c:\R\R-x.y.z\bin; to the path (assuming that you installed R in the location that I suggested).

bulletIf you want to be able to build PDF help files for packages, download and install the MiKTeX LaTeX system; there is also a link to MiKTeX on the Building R for Windows page. Installing MiKTeX will also allow you to create Sweave and knitr LaTeX documents in RStudio, and to compile R Markdown documents directly to PDF files.

Installing R on macOS

bulletVisit the Comprehensive R Archive Network (CRAN) and select a mirror site; a list of CRAN mirrors appears at the upper left of the CRAN home page. I suggest that you use the 0-Cloud mirror, which is the first on the list. Click on the link Download R for MacOS X, which appears near the top of the page; then click on R-x.y.z.pkg (where x.y.z is the current version of R -- R 4.1.0 at the start of the lectures series), which assumes that you are using macOS 10.11 (El Capitan) or higher. You'll also find older versions of R if you have an older version of macOS. Note: As a general matter, you're probably better off updating your macOS to the current version.

bulletTwo macOS installers are provided for the current version of R: one for Macs that use Intel chips and one for newer Macs that use the Apple M1 chip. The former installer is named R-x.y.z.pkg and the latter is namedR-x.y.z-arm64.pkg. At present, I recommend that you use the R-x.y.z.pkg installer whether or not you have a Mac with an Intel chip. The Intel version will work with both kinds of Macs, and there are still some compatibility issues for certain packages associated with the M1-specific version of R.

bulletOnce it is downloaded, double-click on the R installer. You may take all of the defaults.

Building Packages Under macOS, etc. (Optional)

bulletIf you wish to build packages, or use compiled C, C++, or Fortran code in R, or use the rstan package for Bayesian inference, you must install the Apple Xcode developer tools. None of these topics is covered in the lecture series. For macOS 10.7 (Lion) or higher, you can install Xcode for free from the App Store. For earlier versions of macOS, Xcode can be installed from your system DVD or downloaded from the Apple developer website. You do not need Xcode to install pre-built macOS binary packages from CRAN, so this step is unnecessary unless you plan to write your own packages, use compiled code, or use the rstan Bayesian estimation package.

bulletSome R packages include Fortran, C, or C++ code; to build such packages, you will have to install compilers for these languages.The C and C++ compilers are included in the Apple Xcode tools, but you will have to separately download and install a Fortran compiler.

bulletIf you want to be able to build PDF help files, download and install the MacTeX LaTeX system. Installing MacTeX will also allow you to create Sweave and knitr LaTeX documents in RStudio, and to compile R Markdown documents directly to PDF files.

Installing X-Windows on macOS (Optional)

bulletSome R software (e.g., my Rcmdr package) makes use of the Tcl/Tk graphical-user-interface (GUI) builder via the tcltk package to create point-and-click interfaces and to display GUI elements such as progress bars. To use the tcltk package, which is a standard part of the R distribution, you must have the X11 windowing system installed on your Mac. Some other packages that don't use Tcl/Tk, such as the rgl package for dynamic 3D graphics, also require X11.

bulletCheck to see whether the X11 windowing system (X Windows) has already been installed on your computer. If you wish, it should do no harm to skip this step and simply go to the next step to install XQuartz.

For OS X 10.6 and 10.7, the file X11.app should appear in the Utilities folder under Applications in the finder. This application should always be installed under OS X 10.7.

For OS X 10.8 or higher, the file is named XQuartz.app and is no longer included with the operating system. XQuartz.app may also be installed in OS X 10.6 or 10.7.

Note that if you upgrade macOS, you will have to reinstall XQuartz even if you installed it previously.

You may also issue the command capabilities("X11") at the R command prompt. If the response is TRUE then X11 is installed.

bulletIf neither X11.app nor XQuartz.app is installed, install XQuartz from https://www.xquartz.org/. As mentioned, it should do no harm to install XQuartz even if you have X11 currently installed.

      1. Download the disk image (dmg) file for XQuartz.

      2. When you open this file by double-clicking on it, you'll find XQuartz.pkg; double-click on it to run the installer, clicking through all the defaults.

      3. Important: After the installer runs, you'll have to log out and back on to your macOS account, or just reboot your Mac. Also, on first use, XQuartz builds a cache of fonts and so initial performance may be slow; this problem should go away after a short period of time.

Installing R on Linux Systems

bulletVisit the Comprehensive R Archive Network (CRAN) and select a mirror site near you; a list of CRAN mirrors appears at the upper left of the CRAN home page. I suggest that you use the 0-Cloud mirror, which is the first on the list. Click on the link Download R for Linux, which appears near the top of the page. R is available for several Linux distributions (Debian, RedHat, SUSE, and Ubuntu); select your distribution, and proceed as directed.

bulletIf you have a Linux or Unix system that's not compatible with one of these distributions, you will have to compile R from source code; the procedure for doing so is described in the R FAQ (frequently asked questions) list.

Installing RStudio

bulletGo to the RStudio download page, select the free version of RStudio Desktop, click the Download button, and click on the link to the appropriate installer for your operating system (Windows, macOS, or Linux distro). Visit the RStudio IDE home page for more information about RStudio.

bulletOnce it is downloaded, run the RStudio installer and take all of the defaults: In Windows, double-click on the RStudio installer to start the installation; in macOS, double-click on the downloaded RStudio disk-image file, and drag the RStudio icon to the Applications folder.

bulletWhen you first run RStudio, it should detect your R installation and start the R console. To configure RStudio to your taste, select Tools > Global Options (Windows) or RStudio > Preferences (macOS) from the RStudio menus. In particular, I suggest that on the General options screen you deselectRestore .RData into workspace at startup, and set Save workspace to .RData on exit to Never.

bulletIf you encounter difficulties, consult the RStudio troubleshooting guide. or seek help from John or Allison.

Installing R Packages for the Lecture Series

bulletOnce you have installed R and RStudio, you can install additional packages required for the lecture series by typing the following command at the > command prompt in the R Console (and pressing the Enter or return key):

install.packages(c("car", "data.table", "effects", "knitr", "lme4", "rgl", "rmarkdown", "sfsmisc", "tidyverse"))

You can simply copy and paste this command from these installation instructions. Alternatively, you can install packages from the RStudio Packages tab. Be aware that, depending on the speed of your internet connection, it may take some time to download and install these packages and their dependencies.

bulletIf you want to try using C++ code within R (not discussed in the lecture series), also install the Rcpp package, install.packages("Rcpp"). You'll also have to install a C++ compiler, as described in the sections above on building packages under Windows and macOS.

bullet Similarly, if you want to use the Stan Bayesian statistical software via the rstan package (not discussed in the lecture series), you'll have to install the package by the command install.packages("rstan"), and also install a C++ compiler.

Downloading R and RStudio

If you plan to use R, you will need to download R and install it on your computer. It is also advised that you download and install RStudio. RStudio will make it easier to use R and manage your R scripts. 

Two good things about R, are that it is free and it runs on most computers. 

You can download R from: https://www.r-project.org/ 

Figure 1 - R Project Main Page

What is CRAN and why is that a good thing? When you try to download R from the R Project website, you will have to pick a CRAN site to get your download of R. CRAN stands for the “Comprehensive R Archive Network” (CRAN), which is a collection of sites carrying identical material, consisting of the R distribution(s), the contributed extensions, documentation for R, and binaries. 

The CRAN master site is at WU (Wirtschaftsuniversität Wien) in Austria and is mirrored daily to many other CRAN sites around the world. Please use the CRAN site closest to you to reduce network load. 

From CRAN, you can obtain the latest official release of R, daily snapshots of R (copies of the current source trees), as gzipped and bzipped tar files, a wealth of additional contributed code, as well as pre-built binaries for various operating systems (Linux, Mac OS Classic, OS X, and MS Windows). CRAN also provides access to documentation on R, existing mailing lists and the R Bug Tracking system. 

Downloading R You can download R from: https://www.r-project.org/. Simply click on the CRAN link under Download in the list on the left side of the main R site. You can then pick from the list of worldwide CRAN sites for your download. There is a CRAN server at Washington University, St. Louis, MO, USA. That would be a good option. Clicking on the cran.wustl.edu link will take you to the actual download page. 

Figure 2 - Main CRAN Web PSage

Figure 3 - Washington University Saint Louis CRAN Mirror

The simplest option is to download the pre-compiled binary distribution for your operating system. Links for those are at the top of the Downloads page.

Figure 4 - R Downloads Page


Clicking the link on the downloads page will take you to the file repository. If you are trying to download R for OSX, the page will look like this.

Figure 5 - R OSX Downloads Page

You can either select the most recent version of R [arrow A] or download the version with the latest date [arrow B]. Select the download and save it to your Downloads folder. That is it. You are ready to install R on your computer.

If you are trying to download R for Windows, the page will look like this.

Figure 6 - R File Download Folders for Windows

You only need the base install of R. When you click the link for the base folder the next page will look like this: 

Figure 7 - R Download Files for Windows

Select the most recent version of R [arrow A]. This will be the version with the latest date of posting. If you have questions, you can read the version notes [arrow B]. Select the download and save it to your Downloads folder. That is it. You are ready to install R on your computer.

Downloading RStudio You can use R as it was installed on your computer but that involves entering commands from the Terminal prompt and editing R scripts in a separate text editor. RStudio is an easier option and it provides a useful set of tools that will make your work easier. 

You can download RStudio from https://www.rstudio.com/. Click the Download RStudio button near the top of the page. You will want to download the Open Source Edition of RStudio Desktop. This is the free version of the application. Commercial entities must pay for an RStudio license. As a student, you do not.

Figure 8 - RStudio Main Page

Click the Download RStudio link at the bottom of the page [red arrow] and then click the installer for your operating system. Save the RStudio installer download to the Downloads folder on your computer. Be sure to select the RStudio Desktop Open Source License version. You are ready to install RStudio on your computer.

How to install EZR on Windows
There are two methods to install EZR on Windows. The first one is easier, but the version of R and R commander is fixed. The second one is a little bit complicated but it enables installation of EZR on the latest version of R and R commander. However, I recommend the easier method, because EZR may casue an unexpected error according to an update of a package that EZR depends on.

1. Easier method.
Download the following file (EZRsetupENG.exe). EZR is installed along with R and R commander just by running this installer on Windows XP, VISTA, 7, 8 or 10 (both 32- and 64-bit versions). This method installs EZR on R 4.0.3 and R commander 2.7-1. Previous version of EZR should be uninstalled using the uninstall program of EZR before installing the current version of EZR.

Click here to download EZRsetupENG.exe for Windows. (Ver. 1.54 2020/12/24)。

2. Alternative method
1) Download R installer from the The Comprehensive R Archive Network homepage (Download R for Windows, subdirectory: base). Install R.Right-click on the shortcut of R on desktop and select "Property". Add "--sdi" to the command in "Target:" column on the "Shortcut" tab. Double-click this shortcut to run R.

2) Type

install.packages("RcmdrPlugin.EZR", dependencies=TRUE)

after ">" in the R console and push the Enter key.

3) To run R commander, type "library(Rcmdr)", after ">" in the R console and push the Enter key. Answer "Yes" to the question whether the user wants to install packagees that are required by Rcmdr. If this procedure does not work properly, Type
install.packages("Rcmdr", dependencies=TRUE)
after ">" in the R console and push the Enter key to install packages required by R commander, and then, repeat 3). EZR can be loaded by selecting RcmdrPlugin.EZR from the "Tools" > "Load Rcmdr plug-in(s)" menu in the R commander window. Answer "Yes" to "Restart now?".

4) R commander and EZR plugin package will be loaded when R is started, if the following sentences are added to the Rprofile.site file in etc folder in the R folder (C:\\Program Files\\R\\R-X.XX.X\\etc).

options(Rcmdr=list(plugins='RcmdrPlugin.EZR'))
local({
old <- getOption('defaultPackages')
options(defaultPackages = c(old, 'Rcmdr'))
})

5) The default data folder can be changed by right-clicking on this "R" shortcut on the desktop, selecting "Properties", and replacing the folder name in the "Start in:" column on the "Shortcut" tab.

When important files disappear from your computer, your first instinct may be to take immediate, frantic action. While it is important to act quickly, doing so without taking the proper steps can actually worsen your chances of recovering your data. So, before you do anything else, take some time to read these tips.

First and foremost, don't panic. Take some relief in the fact that there's a very good chance that your files are still intact and can be easily recovered. If, that is, you go about it properly. That's because when you delete a file (e.g. by emptying it from the Recycle Bin or Trash Bin), it isn't eliminated right away. Instead, the file system simply flags the disk space as available for use by another program. So, if no other program has used that space yet, then 100% of your file is still there. The same is true even if you repartition or format a disk or drive.

The key is to avoid any read/write activity on the disk at all costs. Surfing the web, downloading programs, installing them and rebooting your machine are all very read/write intensive activities. For this reason, scouring the web for file undelete programs and trying them until you find one that works is about the worst thing you can do. It's entirely possible that the data recovery software you download will actually overwrite the file you are trying to salvage.

You can do a couple of things to prevent this from happening. If the data you are trying to recover is on a removable disk, such as flash card or USB drive, disconnect it for now. If the file you deleted was on your system disk (usually C:\) or an internal hard drive, stop using that computer. Use another machine to download and install a program such as R-Undelete or R-Studio. If you have the technical know-how, go ahead and remove the internal disk from the computer and attach it to a computer running your file recovery tool. Do not install your file recovery software to the same disk that you are trying to recover from. If you cannot remove the drive from the computer, then try using a portable version of R-Studio or R-Undelete installed on removable media.

If your data is lost because the hard drive is failing or being attacked by a virus, then you may want to create an image of the disk. This is a good tactic because it essentially "freezes" the disk in time, preventing any further loss of data. You can then perform your file recovery on the disk image, rather than the disk itself, which may be undergoing further damage as time goes on. Oftentimes, the very act of data recovery can cause further damage to a disk, particularly when the drive is physically damaged. A disk image stops this from happening. Disk images are also useful for complex recovery tasks, such as RAID recovery.

In summary, when you lose a file, make sure you do the following:

  1. Don't panic.
  2. Stop using the disk immediately.
  3. Install data recovery software to another disk or computer.
  4. Create a disk image for advanced recovery or heavily damaged disks.
