R is both a programming language and an environment for statistical computing and graphics. It is a GNU project providing compatibility with the S language and environment developed by John Chambers and others at Bell Laboratories (formerly AT&T, now Lucent Technologies), from 1976 onwards. It provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, ...) and graphical techniques. While it is often the vehicle of choice for research in statistical methodology, it provides a powerful environment for data mining, with a comprehensive collection of analytic tools.
