Exercise

Show me your missingness

Visualizing the missingness in a dataset across variables and objects (cases) is a powerful and intuitive way to understand what kind of missing data we are possibly dealing with. The naniar package has a suite of useful functions to make this visualization step really effortless. Let us put some of these functions to work on the bands dataset you wrangled in the previous exercise.

Visualize the overall missingness in the bands dataset using the appropriate function from the naniar package. Then invoke that function again but group the cases with missing values as closely as possible.
