Exercise

Fix implicit missings using complete()

We are going to explore a new dataset, frogger.

This dataset contains 4 scores per player recorded at different times: morning, afternoon, evening, and late_night.

Every player should have played 4 games, one at each of these times, but it looks like not every player completed all of these games.

Use the complete() function to make these implicit missing values explicit
