Definition - What does R Programming Language mean?
R is a programming language that is primarily used for statistical computing and graphics. It is available for free. Users can compile and run R on various operating systems including Windows, Mac OS X and Linux.
The language is known to be fairly unconventional compared to popular software development languages such as C++ or Java. What makes R stand out from most other languages is that it acts as an interactive statistical environment. R also allows underscores as variable characters, unlike other languages that use them as assignment operators. R is popular among data scientists.
Techopedia explains R Programming Language
Although R is known as a programming language, many programmers refer to it as software that contains a language as well as a runtime environment. Its predecessor language was called "S."
When using R, users can run a programming interface, graphics, a debugger, gain access to certain system functions, and run programs stored in script files. R has been influenced heavily by two other programming languages. These include "S" and the Scheme Repository.
