Arguments

data

plot

Plots the proportions of genotypes or missing values? Default FALSE.

type

Plot types, if type = "barplot" this is the barplot of proportions of missing values; if type= "stacked" this is the stacked barplot of proportions of missing values and genotypes; if type= "dist" this is the dot plot of missing values distribution. Default is not plot.
