R help - Jan 2006 - Question about plotting a hclust tree

Dear R-helpers,

While plotting a hclust tree, is it possible to mark group information on it?

Suppose I have a hclust tree "ClusTree", and I use cutree to cut the
tree into different groups as following

a=cutree(ClusTree,h=10)

How do I mark the grouping info stored in a  while I plot "ClusTree"?


Best Regards....
