Hello all,

I wish to compare two dendrograms (representing Hierarchical Clusterings).

My problems are several:

1) how do I manually create a dendrogram object ?
That is, how can I reconstruct it as an "hclust" object that creates such a
dendrogram, when all I have is the dendrogram image (but don't have the
underlaying distance matrix that produced it) ?
I see that there is a function called "as.dendrogram" But I wasn't able to
find an example on how to use it.

2) Assuming that I have to hclust (or dendrogram ) objects, how can I
compare them ?
After some searching and asking, I found this article:
 http://www.jstor.org/pss/2288117
And a few others that cite it, that gives ideas on how to do this.
But I wasn't able to come a cross a R implementation of it.
Is there ?


Many thanks,
Tal
