The R Project provides a comprehensive, free, open source statistical programming language and environment based on the S language. R is the name of both the language and the environment in which you generally use the language. It’s an interactive environment where the commands you enter generate immediate results that you can use to guide your analyses.

> x <- c(5,4,3,2,5) > mean(x) 3.8

There is an active development and support community using R and it’s been growing more popular in both academic and business communities.
