Here are a couple of tutorials I’ve written to help anyone who’s interested in learning how to produce simple bar charts or simple segmented bar charts in R, given that you have some data stored in a CSV file that you can use. Please leave any comments if there are ways I can make this information more clear and useful. Thanks!
mnm-data (Note: This is an Excel XLS file! You need to download it and re-save as a CSV for the R examples to work.)
