The R programming language is used for data analysis, data manipulation, graphics, statistical computing and statistical analysis. In short, R helps you analyze data sets beyond basic Excel file analysis. The R programming language and development environment are open source and have grown in popularity since its conception in the early 90s by Ross Ihaka and Robert Gentleman at the University of Auckland, New Zealand. The R Development Core Team is a community of developers engaged in development and support of the R project from the R Foundation - a not for profit organization providing support for R and other innovations in statistical computing. R is a free software environment that runs on a wide variety of UNIX platforms, Linux, Windows and Mac OS.
