[R] bootstrapping for clustering

Dear R-listers,

Is anyone familiar with a package that would perform bootstrapping on 
species/site matrices for clustering ? So far I have been using the 
vegan package to generate trees (Bray-Curtis index), but I would like 
to associate a certainty to each node (similarly to a phylogenetic 
If no package exist, I would know how to generate bootstrapped matrices 
of distance, but how could I plot the results ? Graphically, I am 
looking for something similar to what is available from the pvclust 
package (my understanding is that pvclust makes covariance clustering 
from dataframes, and it cannot be used with matrices to generate 
Bray-Curtis similarity dendrograms?)

Please forgive my ignorance!

Thank you in advance,
eric pante
