I don't think the result from _princomp _ should be rotated.
The definition of "principal components" explicitly indicates that the
result is to have axes that are uncorrelated and line up in directions
of maximum variance.
If I am wrong,I hope some one else to point it out.
They can be, whether they should be is another matter. See the
Statistical Complements to MASS3 at
http://www.stats.ox.ac.uk/pub/MASS3/Compl.shtml for some examples and
references.
The original post is starting from false premises: there is no `factanal
package', and the varimax function in stats is not confined to the results
of factanal().
If for some reason you want to use the so-called `principal component
factor analysis', you could make use of one of the several statistical
systems with names starting with S that provide it, or write your own R
code.

Dear R users
the factanal pacakge is always MLE, which package can do varimax
rotation with the results from princomp ?
thank you
