Professor Hennig; Thank you for the input; Just one thing about the corrected Rand in the function "cluster.stats" in the fpc package, is the expectation used in the correction is the one by Phipps and Arabie paper in JoC..Thaks again

> Dear R users, I am interested in clustering in R. In SAS we have some criteria for determining the number of clusters using the PROC CLUSTER procedure, which are "CCC" cubic clustering criterion (Sarl 1981), Psuedo F (PSF), and Psuedo T square (PST). My question is do thsese criterion exists in R, I tried to search and got one hit (BIC) in Mclust, which I am aware of, any input is greatly appreciated.

Function cluster.stats in package fpc gives you some more. (See Gordon book reference on the help page.)
