Similarity between clusters generated by hclust + cutree

Wed, Feb 25, 2009 7:49 AM

Dear friends

I have clustered some objects using the hclust algorithm, with method ward. I 
then cutree with 48 classes. 

distPredTurn<-as.dist(resultMatrix)
hctr<-hclust(distPredTurn,"ward")
cutree(hctr,k=NC)

I would like to estimate the similarity between each pair of the 48 clusters, 
for example as (1-distance or dissimilarity) between the centroids.

Any clue on how I can do that?

Regards
