Rは統計計算とグラフィックスのためのフリーソフトウェア環境であり、S言語の方言である。 プログラミング言語. It was created by Ross Ihaka and Robert Gentleman at the University of Auckland, New Zealand. R is considered an alternative implementation of S, with semantics derived from Scheme, which introduced powerful features like lexical scoping not present in early S. The design of R draws on Scheme, an example of how programming languages research influences practical tools for statistics.
