R packages are extensions to the R statistical programming language. R packages contain code, data, and documentation in a standardised collection format that can be installed by users of R, typically via a centralised software repository such as CRAN (the Comprehensive R Archive Network).[1][2] The large number of packages available for R, and the ease of installing and using them, has been cited as a major factor driving the widespread adoption of the language in data science.[3][4][5][6]
Compared to libraries in other programming language, R packages must conform to a relatively strict specification.[3] The Writing R Extensions manual[7] specifies a standard directory structure for R source code, data, documentation, and package metadata, which enables them to be installed and loaded using R's in-built package management tools.[3] Packages distributed on CRAN must meet additional standards.[3][8] According to John Chambers, whilst these requirements "impose considerable demands" on package developers, they improve the usability and long-term stability of packages for end users.[3]
