[R] cluster - identify variables contributions to clusters of cases

2007-07-27 Thread Alexander.Herr
Hi List,

How would I go about best identifying the variables contributing most to
the specific clusters?
eg using either aglomerative or partitioning methods, but with mixed
variables (ie including categorical) eg:

factor(as.integer(runif(min=1, max=5,nrow(USArrests-t1
as.data.frame(cbind(USArrests,categ=t1))-test
agnes(test,metric=gower, method=ward)-test1
cutree(test1,k=5)-clust


?where to go from here?

Any hints appreciated
Thanx
Herry

I am not sure this might help, but you are perhaps lookign at variable
selection. There is a 2006 JASA paper by Raftery and Dean which may
help.

Many thanks,
Ranjan
