vis_miss: Visualise a data.frame to display missingness.

Description

vis_miss provides an at-a-glance ggplot of the missingness inside a dataframe, colouring cells according to missingness, where black indicates a present cell and grey indicates a missing cell. As it returns a ggplot object, it is very easy to customize and change labels, and so on.

Usage

vis_miss(x, cluster = FALSE, sort_miss = FALSE, show_perc = TRUE)
