[Rd] Distance between clusters

[Corrado]

Dear friends

I reformulate the question. I think I did not formulate it properly.

I have some data on some sites. I can define a dissimilarity between each pair 
of sites. Using this dissimilarity, I have clustered the sites using the 
hclust algorithm, with method ward. I then obtain 48 clusters, by cutting the 
tree using cutree with k=48. 

I would now like to estimate the distance between each pair of the 48 
resulting clusters. I have read the documentation, but I cannot find a 
solution.

Any clue on how I can do that?

This is a snippet of the code:

distPredTurn<-as.dist(dissimilarityMatrix)
hctr<-hclust(distPredTurn,"ward")
cutree(hctr,k=48)
