[R] Analyzing dendrograms

Ladies and Gentlemen,

As Johan Lindberg points out, the documentation for handling dendrograms
is sparse....Does anyone know who is responsible for or working on 
development of tree methods and objects? I've written a couple of scripts   
for my own use to translate between parenthetical (A(B(CD))) or binary  
A00 B10 C11 D11 tree formats and cluster objects in R, but as an 
inexperienced programmer have had difficulty integrating them with the 
existing framework--I'm trying to write some resampling routines and 
sensitivity tests for tree objects.

Perhaps this question should go to the r-devel list instead....
