Hello all,
I have a set of data points, which I have pair distances for. I managed to create dendrogram for this data set using diana() in R, however this only gives me the tree and not the clusters themselves. I am trying to determine clusters using Calinsky and Harabasz Index (CH Index). I, however, cannot find how to accomplish this using R. Is there anyone who could help me with this? I searched R documentation for implementation of CH index and found some things but not the clustering. Thanks a bunch.

Sincerely,
Arif.
