We typed the function help and then specified the argument (package = cartography). We could have easily just typed the function help(), without defining an argument.

In the Help tab, we see information about the package cartography, including all the functions within the package. This is super useful, and something you’ll want to consult if you get stuck.

If we click on the barscale function, it takes us here:

We now see a display of all arguments associated with the function barscale and what they mean.
