R is a free software environment used for statistical computing and graphics. It is developed by The R Project for Statistical Computing and is based on the "S" system developed by Bell Laboratories. The program compiles and runs on Windows and OS X, and Linux platforms.
The environment features the R programming language, which includes loops, user-defined recursive functions, conditionals, and input and output facilities. The project provides a variety of software facilities for data manipulation, calculation, and graphical display. It offers data handling and storage capabilities, a collection of statistical analysis tools, and the ability to perform calculations on arrays, such as matrices and spreadsheets. The program can also analyze data and display it on-screen or on hardcopy.
Also, R can be extended via packages that are available through the R distribution and Comprehensive R Archive Network (CRAN) Internet sites. These packages are often user-created and provide capabilities such as reporting tools, specialized statistical techniques, graphical devices, and support for importing and exporting additional formats.
The R environment is primarily used among data miners and statisticians. The project provides an impressive amount of statistical analysis features and allows you to add to its capabilities through packages, as well. Overall, R is a high-quality statistical computing and graphics environment that you can download for free.
