R is installed on computers in the student computing labs\classrooms, graduate student computer labs and classroom podium computers. C:\R_Library folder and an environment variable (R_LIBS) has been added so that users can install packages. A list of packages preinstalled on lab computers is in Q:\Public\R 3.x.x\R packages.txt

Extra steps are needed to make sure that students have access to R packages in the lab environment.
To add packages to the default location in C:\Program Files\R\Library, the user must right click on the R icon and run R as an adminstrator. The instructions below don't require admin rights to install R packages and can be used on any computer.
Adding Packages to R on student lab computers.
Additonal steps are required for student lab computers because users are not given Administrator rights.
1. Add a folder named R_Library to the C: drive. Give Authenticated Users Modify rights to the directory.
2. Open the Environment Variables window by going to Control Panel > All Control Panel Items > System > Advanced system settings > Environment Variables, or by searching Environment Variables in the Windows Search bar.
3. Click "New..." to create a new Environment Variable entry with the following parameters:
Variable name: R_LIBS
Variable value: C:\R_Library
4. Click "OK" on the Edit User Variable and Environment Variables windows. Logout and login so the system variable is created before going to the next step.
5. Launch R and select Packages | Set CRAN Mirror... from the menu bar. R can be launched from either the desktop shortcuts created before, or multiple other locations, depending on the installation location. If the default location was used, the RGui can be launched from "C:\Program Files\R\R-4.0.2\bin\i386\Rgui.exe" for the 32-bit version, or "C:\Program Files\R\R-4.0.2\bin\x64\Rgui.exe" for the 64-bit version. Either version can be used for this procedure.
6. Scroll down to find the USA (OR) CRAN mirror and select it, then click OK.
7. To install multiple packages and their dependencies enter the install command in R. For example: "install.packages(pkgs=c( "abind", "ade4", "adehabitat"))". This will usually depending on what packages instructors need for classes. If a student requests a specific package, check with the instructor to see if the package is needed and check to make sure the package is compatible with the current version of R.
8. Verify that the packages have been installed by checking the folders in the C:\R_Library directory.
