Hi, I've a dataset with discrete data and several groups and in one group I have also missing values (NA). When I use table and barchart to visualize the counts I never get a bar for NA in the barchart although it appears in the result of table. Is there a possibility to get this bar too?
Please give a reproducible example, because it's not clear to me what exactly is supposed to be NA. -Deepayan
