Subject: Collapse UP a dendrogram
I created a dendrogram (ddg0) using hclust in the usual way. I want to
collapse UP the tree in various ways, that is, from the leaves up to the
root. Optimally, I would give the id of a member of a final split in ddg0,
and return a new ddg1 with that split collapsed. Alt, I could give a depth
to collapse up to (such that ddg1 would have n fewer levels than ddg0). That
sort of thing. I could, of course, program this myself, but it seems like
something that is so obviously needed that there is very likely to be a
package that does it already. Is there? TIA 'Jeff
