Make jitter work with incomplete categorical variables

[hanneoberman]

[hanneoberman]

The problem is as follows: The missing data points are not plotted on top of the axes when jitter is used.

library(ggmice)
library(ggplot2)
ggmice(mice::nhanes, aes(age, bmi)) + geom_point()

ggmice(mice::nhanes, aes(age, bmi)) + geom_jitter()
#> Warning: Removed 9 rows containing missing values (geom_point).

Maybe check if jitter can be applied either horizontally or vertically, depending on the missingness? E.g. geom_jitter(width = 0)

Alternative: VIM::marginplot()-like functionality

The current version does not have this issue

library(ggmice)
library(ggplot2)
ggmice(mice::nhanes, aes(age, bmi)) + geom_jitter()
