R est un environnement logiciel libre pour le calcul statistique et la représentation graphique, et un dialecte du langage S. langage de programmation. 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.
