You must have the mva package if you are doing principle
components.  Look at the help for it.  You will see "varimax" as
one of the topics, and "factanal" as another.  I think that is
what is available.  I don't think you can do varimax rotation on
principal components (unless you write it yourself, assuming that
it is meaningful).
