install.packages()
   get_help() docs


Description

The install.packages() function comes with R and is part of the Base R {base} package.

We use this function to install packages, aka libraries, onto your computer. Libraries only need to be installed one time. To load an installed library, use the function library().

If you need to install a package from a non-default database (i.e. not CRAN), this function may or may not work.

Conceptual Usage

install.packages("name of package to install in quotes")

install.packages(c("array", "of", "package", "names", "to", "install"))

Examples

# Install the viridis package
install.packages("viridis")
