Excercise
Choose one of these to explore. Depending on your confidence, choose the same package as your neighbor (to go through it together) or a different one (and then share what you learn). Each package will have sample data that works with their examples. Install the package, and then work through some examples. Practice changing some arguments. Then try it on the NLSY data. Save your code in a new file, commit, and push!
