How do I add sample annotations to this data?

I was able to generate this dot plot using ggplot2 from scratch. I would like to add sample annotations (similar to the ones you'd see in heat maps where they annotate clusters). I have another data frame containing sample IDs and their respective subtypes. Pseudocode would be appreciated.

maybe try a simple facet_grid(~group,scales="free",space="free") where group is the column in you dataframe containing the sample annotation. Without any example it will be difficult to help you.

So this absolutely serves the function I wanted to achieve, Thank you so much for that. Can we make it colorful though :P Also, is it possible to wrap text, for the one that seems to be cut off?
