gg_miss_var: Plot the number of missings for each variable

Description

This is a visual analogue to miss_var_summary. It draws a ggplot of the number of missings in each variable, ordered to show which variables have the most missing data. A default minimal theme is used, which can be customised as normal for ggplot.

Usage

gg_miss_var(x, facet, show_pct = FALSE)

Value

a ggplot object depicting the number of missings in a given column

Arguments

x

a dataframe

facet

(optional) bare variable name, if you want to create a faceted plot.

show_pct

logical shows the number of missings (default), but if set to TRUE, it will display the proportion of missings.
