equivalent to ggplot2::ggplot output, with a few important exceptions:
The theme is set to theme_mice.
The color scale is set to the mice::mdc colors.
The colour aesthetic is set to .where, an internally defined variable which distinguishes
observed data from missing data or imputed data (for incomplete and imputed data, respectively).
Arguments
data
An incomplete dataset (of class data.frame), or an object of class mice::mids.
mapping
A list of aesthetic mappings created with ggplot2::aes().
