Packages in R<\/h2>\n

A package is a collection of R functions, data, and compiled code in a well-defined format.<\/em> Packages are being stored in the directory called the library.\u00a0R comes with a standard set of packages. With the help of the search()<\/em> command, you can find all the list of available packages that are installed in your system.<\/p>\n
