R Programming Language (Analysis Software for Statistics & Data Science) R is a programming language and software that is becoming increasingly popular in the disciplines of statistics and data science.. R is a dialect of the S programming language and was developed by Ross Ihaka and Robert Gentleman in the year 1995. There are now a number of books which describe how to use R for data analysis and statistics, and documentation for S/S-Plus can typically be used with R, keeping the differences between the S implementations in mind. The R language is widely used among statisticians and data miners for developing statistical software and data analysis. Scatter plot in R with different colors .
