R help - Feb 2014 - How to assign membership after hierachical clustering(agnes{cluster})

Dear list,

My Problem Setting Looks as Follows:

I have a list of object [O1,O2,O3,O4,......O6000], on which a pairwise
distance matrix is defined, called dist.matrix.

After that, a agnes has been conducted on the distance matrix.

agn1<-agnes(dist.matrix,method="ward")

even cutted

agn1_cut<-cut(agn1,h=9000)         #something like this

Now how can I get back the cluster membership?

Another difficulty here is , is that possible that I can get back the
cluster preserved in the order of original list of object.(my dist.matrix
is showhow still order preserved)



By the way, for a reproductive sample code, I will point to

Examples in
http://stat.ethz.ch/R-manual/R-patched/library/cluster/html/agnes.html

How to get cluster label for agn1, for instance




I have been googled for 2 hours. I am wondering why no one has question
like that before
thank you very much.

Did you look at the help for agnes.object as directed by the help file
that you yourself linked in your email?

If none of those components meet your needs, as.hclust() - also
pointed to by the agnes.object helpfile - might give you what you
want.
