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?
Thanks in advance Sigbert Klinke ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
