R programming language
The R programming language is a computer programming language and software environment for statistical computing. Statisticians and data miners widely use it to perform complex analysis.
R was first introduced in 1993. It was created by Ross Ihaka and Robert Gentleman at the University of Auckland, New Zealand as an implementation of the S programming language. Like S, which was developed by John Chambers while he was at Bell Labs in the late 1970s, R was created to "turn ideas into software quickly and faithfully."
R is an interpreted language, and its principle user interface is a command line. Native data structures of R include vectors, scalars, matrices, lists, and data frames, which are similar to a table in a relational database. R performs matrix arithmetic with a speed comparable to MATLAB.
