[37], Although used mainly by statisticians and other practitioners requiring an environment for statistical computation and software development, R can also operate as a general matrix calculation toolbox – with performance benchmarks comparable to GNU Octave or MATLAB. The Register, 7 February 2011. R is a programming language is widely used by data scientists and major corporations like Google, Airbnb, Facebook etc. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. Installation from within R fails. These packages are developed primarily in R, and sometimes in Java, C, C++, and Fortran. A list of changes in R releases is maintained in various "news" files at CRAN. A generic function acts differently depending on the classes of arguments passed to it. Objects in the function body remain local to the function, and any data type may be returned. [15] S was created by John Chambers in 1976 while at Bell Labs. Select the installerlink that corresponds to your operating system (e.g. Learn More about RStudio features Introduced a flexible condition handling mechanism for signalling and handling condition objects. You will learn how to install and configure software necessary for a statistical programming environment and describe generic programming language concepts as they are implemented in a high-level statistical language. Please see the R FAQ for general information about R and the R Windows FAQ for Windows-specific information. R is an interpreted language; users typically access it through a command-line interpreter. It includes machine learning algorithms, linear regression, time series, statistical inference to name a few. Considered by its developers stable enough for production use. Functions are first-class and can be manipulated in the same way as data objects, facilitating meta-programming, and allow multiple dispatch. It compiles and runs on a wide variety of UNIX platforms, Windows and MacOS.
