What's in a package?
Sometimes we need to view all the functions that are built into an R package.
This is done in the same way you would list variables in your workspace, using the ls function. Note that the package must be loaded before you run the ls command.
Usage: Getting a list of functions inside the dplyr package
library(dplyr)
