R help - Nov 2010 - varclus in Hmisc vs SAS PROC VARCLUS

Hi,



I'll apreciate your guidance on how can I re-create the output from SAS PROC
VARCLUS in R. I've found the varclus function in Hmisc. However, is it
possible to use that function to compute for each variable the 1-R**2 ratio
(this is the ratio of 1 minus the R-squared with Own Cluster to one minus
the R-squared in the Next Closest cluster)?



Thanks in advance for any help,



Lars.

My impression is that varclus from the Hmisc library is very
convenient to use when you want to get an idea of the correlation
among predictor variables in a regression setting, but if you want
to perform cluster analysis in general, you may be better off using
a different function in R, such as hclust or kmeans.
