I really like your varclus function Frank.  I have a question about the
quartimax rotation of the 1st two eigen vectors as the SAS VARCLUS algorithm
dictates.  According to the SAS user guide example of VARCLUS the only thing
needed to perform the cluster analysis is the variable correlation matrix. 
Is that the case?  The following is the SAS user guide example website.
