R (Programming Language)

Description: R is an open source programming language used for statistical computing and graphics that is supported by the R Foundation for Statistical Computing. It is widely used by statisticians and data miners for developing statistical software and data analysis. Functions and results of analysis are all stored as objects, allowing easy function modification and model building. 

Platform: Windows, Mac, Linux, Unix
Cost: No charge (Open Source)


Overview/License

R is an open source programming language used to implement a variety of stastical and graphical techniques. It compiles and runs on a wide variety of UNIX platforms, Windows and MacOS. R provides the language, tool, and environment in one convenient package. R is an implementation of the S programming language. R was created at the University of Auckland, New Zealand and is now developed by the R Development Core Team. R uses a command line interface. The capabilities of R are extended through user-submitted packages. Several graphical user interfaces are available.  SAS integrated R within SAS/IML Studio. R can also be called from SPSS.

Graphical User Interfaces (GUI)


R has a library of GUI's that implement a wide variety of statistical and graphical techniques, including linear and nonlinear modeling, classical statistics tess, time-series analysis, classification, clustering and others.

Among the various GUI's available for R:

R GUI for Data Mining:
