R is a computing environment primarily intended to perform statistical computations with support for reports, databases, graphics etc. It, with a simple yet powerful programming language called S, allows to perform various complex data manipulations and analysis. It includes vast array of support package libraries created to provide specialized functionalities to special domains. R language is widely used among statisticians and programmers for developing statistical manipulation and data analysis.
R was created by Ross Ihaka and Robert Gentleman at the University of Auckland, New Zealand, and is currently managed by R Development Core Team. It is licensed under the GNU General Public License. It’s first version was release in August of 1993 and its latest version R 3.3.2 (Sincere Pumpkin Patch), at the time of this writing, was released in October of 2016.
It is primarily written in C, Fortran and R itself and works with many operation systems. Some of its features include:
The Comprehensive R Archive Network (CRAN) is an additional facility that maintains R based packages, other than R core packages, designed to support many specialized functions. It has more than 7000 packages currently available. R has its own comprehensive documentation in LaTeX-like documentation format; this is available on-line in a number of formats and in hardcopy also.

It is primarily written in C, Fortran and R itself and works with many operation systems. Some of its features include:
- An efficient programming language S with flexible constructs such as loops, functions, etc.
- Command line interface & many graphical user interfaces.
- Support for many mathematical and statistical operators.
- Support for arrays and matrices arithmetic operations.
- Strong object oriented programming support but also allows procedural programming with functions.
- Vast tools for data analysis and manipulation.
- Predefined functions for known statistical models.
- Data handling and storage facilities.
- File handing and manipulations.
- Graphics that support mathematical symbols with publication quality output.
- Highly extensible with packages consisting library of functions.
- Scripting language support to work with different operating systems.
- Runtime linkages with C, C++, Fortran, Java, .Net programs.
- System level commands issue facility.
- Supports compressing and archiving of data files.
