Using miss_scan_count
You have a dataset with missing values coded as "N/A"
, "missing"
, and "na"
. But before we go ahead and start replacing these with NA
, we should get an idea of how big the problem is.
Use miss_scan_count
to count the possible missings in the dataset, pacman
, a dataset of pacman scores, containing three columns:
year
: the year that person made that score.initial
: the initials of the person.score
: the scores of that person.
