Add functionality with packages
To add functionality to base R
, you need to install and load packages. For this exercise, the dplyr
package is already loaded. You can confirm that the dplyr
package is loaded and available for use by running the sessionInfo()
command to view your R
session status including all loaded packages.
You will then use the library()
function to load the package Hmisc
and run sessionInfo()
again to confirm that the Hmisc
package was loaded as well.
This exercise is part of the course
