Load an R Package
There are basically two extremely important functions when it comes down to using R packages:
install.packages(), which as you can expect, installs a given package.library()which loads packages, making them available to use in your R workspace.
To install packages, you need administrator privileges. This means that install.packages() will not work in the DataCamp interface. However, the most popular CRAN packages are already installed on our servers. You can load them with library().
