# Cubic clustering criterion in R

Does anybody know if any package calculates the cubic clustering criterion (CCC) index in R to aid the selection of optimal number of clusters?

Not exactly what you are looking for but the command cluster.stats from the R package fpc might be helpful. –  user10525 May 24 '12 at 23:43
@Procrastinator Please, make this an answer; this sounds like a good advice, according to the author of the fpc package on R-help. I also gave some pointers on related threads. –  chl May 26 '12 at 10:29
@chl Thanks for your comment. I have to admit that I do not know the area enough to make a defensible answer. I based my comment on the link you posted, the description on the manual and a quick search. –  user10525 May 26 '12 at 10:33
