Overview
R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues.
R is the fastest growing statistical software/language and is rapidly overtaking all others (e.g. SPSS, STATA, & SAS in popularity and use.) For a view of where it's come from, check out R: Past and Future History (from 1998).
RStudio Desktop is a powerful and productive user interface for R. It’s free and open source, and works great on Windows, Mac, and Linux.
