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
See the varclus function in the Hmisc package.

Hi All,
I'd like to build a package for the community that replicates the output
produced by SAS proc varclus. According to the SAS documentation, the
first few steps are:
1. Find the first two principal components.
2. Perform an orthoblique rotation (quartimax rotation) on eigenvectors.
3.
