R is an open-source data analytics and data visualization software program. It is used for statistical modeling, both linear and non-linear, usual statistical tests, time-series analysis, and clustering, etc. That means it is free and recognized by even peer-reviewed science journals. It was developed by Ihaka and Gentleman in NewZealand. However, you need to give commands unlike in other statistical programs such as SPSS. An exceptional advantage of R scripts that you create can be shared by others. So, we can make other lives much easier.

This is a product developed by contributions from extraordinary people living all over the world. The program – known as “R and R” – was initially written by Robert Gentleman and Ross Ihaka off the Statistics Department of the University of Auckland.
