R は統計計算とグラフィックスのためのフリーソフト(GNU-style copyleft)である。
ニュージーランドAukland大学のDr.RossIhaka,Dr.RobartGentlemanが開発した。
RはSに操作環境などが良く似ており, Sで動作するものはRでもほとんど変更なしに動作する。

”解説
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.
R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, ...) and graphical techniques, and is highly extensible. The S language is often the vehicle of choice for research in statistical methodology, and R provides an Open Source route to participation in that activity.
