Gives you 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)
Arguments
x
a data.frame
cluster
logical TRUE/FALSE. TRUE specifies that you want to use
hierarchical clustering (mcquitty method) to arrange rows according to
missingness. FALSE specifies that you want to leave it as is.
sort_miss
logical TRUE/FALSE. TRUE arranges the columns in order of
missingness.
Details
vis_miss visualises a data.frame to display missingness. This is
taken from the visdat package, currently only available on github:
