Here is probably a trivial question but I do not know how to work out the answer As I have relatively few data I'm able to use the pam function to do clustering ( "plot(pam(mydata,3)" ); though I found out in the help how to work out the optimal nb of clusters (thanks to all concerned!) I still need to identify the points in the first plot (datas around the centroids) , I do not seem to be able to use the identify function as the profile plot is produced directly after the 1st one I would need to labels the points in the 1st plot. How do I get to do that? Thanks Anne [[alternative HTML version deleted]]
