# Chapter 1 What is R?



According to the official webpage:

• 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 can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R. http://www.r-project.org/about.html

The R language is widely used among statisticians and data miners for developing statistical software and data analysis.
