R is a statistical software program. RStudio is a user interface for R that organizes the windows you see while using R. The default interface for R on Macs is usually sufficient, though users who are used to another statistical software program, such as Stata, may prefer the familiar interface of R Studio. Both R and RStudio are free and open source.

If you have any difficulty while installing the software, bring your laptop to the Help Desk in Clapp Library or email helpdesk@wellesley.edu with a description of the problem.
