R help - Jul 2009 - hierarchical clustering - variable selection

Hi List,

I am looking for a procedure that allows selection of variables in a clustering
attempt.

Specifically I am searching for a way of selecting out noise variables from a
set of numeric/categorical variables (or of course selecting
"non-noise" variables).

The procedure should work with gower/ward metric/method. So far I have only
found procedures that deal with numerical variables.

Any hints to packages/procedure would be appreciated

Thanks
Herry

varclust() in the Hmisc package might be what you are looking for.
