Abstract

R is a statistical computing environment having facilities for data manipulation, calculation, graphical display etc. R is also a free implementation of S language, which was developed for statistical computing and graphics by John Chambers of Bell Labs. A commercial version of S is also available as S+® from Insightful Co. R was developed initially by Ross Ihaka and Robert Gentleman. R is developed as open source software and available free for use. R has an effective data handling and storage facility, a suite of operators for calculations on arrays, in particular matrices; a large, coherent, integrated collection of intermediate tools for data analysis; graphical facilities for data analysis and display. RStudio is an integrated development environment (IDE) for R. It includes a console, syntaxhighlighting editor that supports direct code execution, as well as tools for plotting, history, debugging and workspace management. RStudio is available in open source and commercial editions and runs on the desktop (Windows, Mac, and Linux) or in a browser connected to RStudio Server or RStudio Server Pro (Debian/Ubuntu, RedHat/CentOS, and SUSE Linux).
