What is R?<\/h4>\n

R is a programming language used for scientific computing and graphics. The roots of R language can be found in the S programming language which was developed at Bell laboratories in the 1970s, mainly by John Chambers. The R language was conceived in the early 1990s by Ross Ihaka and Robert Gentleman. R also refers to the software environment which is used to run the programs written in R. The R environment is free and open-source software. R as a programming language has gained wide popularity in recent years and it ranks among the top programming languages for data science. This popularity has resulted on account of various factors like ease-to-learn, excellent data manipulation and visualization tools, thousands of contributed packages on CRAN (Comprehensive R Archive Network), ability to create your own packages, and a large developer community.<\/p>\n

An integrated development environment (IDE) is a software application that provides a facility to programmers for easy software development. An IDE normally consists of a source code editor, build automation tools and a debugger. There are other IDEs for R like Visual Studio and Eclipse, however, RStudio is considered to be the best available IDE for R programming.<\/p>\n
