S (programming language)
From Wikipedia, the free encyclopedia
S is a statistical programming language developed primarily by John Chambers and (in earlier versions) Rick Becker and Allan Wilks of Bell Laboratories. The aim of the language, as expressed by John Chambers, is "to turn ideas into software, quickly and faithfully".
There are two implementations of S; a free implementation, the R programming language, and a commercial implementation, Insightful's S-PLUS.
Version 4 of S, often abbreviated S4, provides advanced object-oriented features. S4 classes differ markedly from S3 classes.
