RStudio is a user interface for R that organizes the windows that you see while using R. We recommend that Windows users install both R and RStudio, as the default R interface on Windows is not user-friendly. RStudio is also particularly helpful for those who are used to Stata. The program is free and open source, and installers are available on the above Mac and PC pages.
STAT Course Catalog can be found here. Courses at or above STAT160 utilize R. Introductory STAT courses outside the math department are sometimes taught in R as well.
