miss_var_which

data

It can be helpful when writing other functions to just return the names
of the variables that contain missing values. <code>miss_var_which</code> returns a
vector of variable names that contain missings. It will return NULL when
there are no missings.

Missing values are ubiquitous in data and need to be explored and
handled in the initial stages of analysis. 'naniar' provides data structures
and functions that facilitate the plotting of missing values and examination
of imputations. This allows missing data dependencies to be explored with
minimal deviation from the common work patterns of 'ggplot2' and tidy data.
The work is fully discussed at Tierney & Cook (2018) <arXiv:1809.02264>.
