  • $\begingroup$ Not exactly what you are looking for but the command cluster.stats from the R package fpc might be helpful. $\endgroup$

  • $\begingroup$ @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. $\endgroup$

  • $\begingroup$ @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. $\endgroup$

  • $\begingroup$ you could ask them to move it to stack-overflow and they could do good. The answer already exists and is useful here, showing that the venn diagrams of the subject areas in practice have overlap while in theory they do not. $\endgroup$

It is included in NbClust and to be used via the option index = "ccc", e. g. 

I_ccc <- NbClust(X, distance="euclidean", min.nc=2, max.nc=8, method = "complete",
        index = "ccc")
