In this article created by Donato Teutonico, the author of Instant R Starter, we will learn the features of R. R is a high-level language and an environment for data analysis and visualization. It provides an environment in which you can perform statistical analysis and produce high-quality graphics. It is actually a complete programming language, derived from the statistical programming language S. It has been developed and is maintained by a core of statistical programmers, with the support of a large community of users. It is most widely used for statistical computing and graphics, but is a fully functional programming language well suited to scientific programming, data management and data visualization in general.
The interaction with the R system is mainly command-driven, with the user typing in text and asking R to execute the specific command. As soon as you start R, a session will be opened, on which the commands may be introduced and the expression executed. Complex procedures can be implemented in scripts, which are executed as soon as they are loaded into the system or, more efficiently, as function, which can be loaded in the system and used when needed.Read First steps with R in full
