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
This exercise is part of the course
Dealing With Missing Data in R
Exercise instructions
For the frogger
dataset:
- Use
complete()
fromtidyr
on thetime
andname
variables to make implicit missing values explicit.

# Print the frogger data to have a look at it
___
# Use `complete()` on the `time` and `name` variables to
# make implicit missing values explicit
