R help - Jun 2005 - Selecting input and output variables in clara (cluster-package)

Moin,

is there any possibility to choose the input variables which are
involved in the analysis,
 " ..., and each column correspondends to a variable. ..."
(R-Reference-Manual)
or do I have to delete them from the data.frame?

An then I'd like to get the original dataset with the classification of
the cluster, at the moment i do it this way

clusterFrame <- merge(claraResult$clustering,claraResult$data,by = 0,
all.x = TRUE);


Thanks Matthias
