What is R?
R is a popular and free software environment for statistical computing and graphics, is open source.
R is available as Free Software under the terms of the Free Software Foundation’s GNU General Public License.
R is currently available as a deployable package, and is installed by default on all of our teaching stations. The most current deployable version of R is 4.1.0, 64-bit.
Starting in Fall 2021, packages for R (and RStudio) will be not be pre-loaded on Whitman Computers. R Packages are installed in the User's H Drive, and should follow the user, so faculty are encouraged to assign their students an exercise to prepare their R Environment for the semester prior to utilizing R.
