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.
