Install and Load Packages
Packages already included in the initial installation may not have functions that you need. In R, you can easily install and load additional packages provided by other users.
- To install packages:
You can either use install.packages() function
or click Tools > Install packages. Write the package name in the dialog, then click install.
- Once you install the package, you need to load it so that it becomes available to use. Simply use library() function.
