Exploring missingness dependence
To learn about the structure of the missingness in data, you can explore how sorting changes how missingness is presented.
For the oceanbuoys dataset, explore the missingness with vis_miss(), and then arrange by a few different variables
This is not a definitive process, but it will get you started to ask the right questions of your data. We explore more powerful techniques in the next chapter.

Dealing With Missing Data in R
Exercise instructions
Using the dataset, oceanbuoys:
- Arrange by the variables,
year,latitude, andwind_ewusingvis_miss().
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Arrange by year
___ %>% arrange(___) %>% vis_miss()
# Arrange by latitude
___ %>% ___(___) %>% vis_miss()
# Arrange by wind_ew (wind east west)
___ %>% ___(___) %>% ___()
