Method how to add centroid circles? from nmds command


If I do an nmds analysis using mothur, which I subsequently plot in R. How can I add centroid circles (not sure what they are called) around samples belonging to the different communities? I know you can do it using different R packages where the nmds analysis is an option. But is there a way of adding these circles (using R?) from the nmds output produced by Mothur?


There isn’t a way to do it in mothur.
