[R] 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. ############################## [[alternative HTML version deleted]]

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.
