R é um ambiente de software livre para computação estatística e gráficos, e um dialeto da linguagem S. linguagem de programação. 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.
