R help - Dec 2004 - UPGMA

R-help folks:

Thanks in the past for your help.  I have another question that I hope 
has a simple answer.  I have searched the R home pages and the R-help 
archives with no hits.  How can I cluster data in R using UPGMA?

I am not subscribed to the list (can't keep up with all the traffic!), 
so I would appreciate it if you could email directly to me (or to the 
list and to me).

Thanks,
Tom Isenbarger

library(cluster)
?agnes		# uses method="average" aka UPGMA by default

or
?hclust		# has  method="average" as well.


I've added a \concept{} to agnes such that from the next version
of "cluster", 
   help.search("UPGMA clustering") 
will find agnes().
