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.
