[R] Unscaled factanal()

I'm using R 2.8.0.

Is there a way of doing factor analysis with factanal() that keeps it 
from scaling the covariance matrix?

Apparently, even if covmat=S is used, the function effectively 
converts to a correlation matrix before doing the factor analysis.

This may be the best choice in most instances, but occasionally I'd 
like to perform the analysis directly upon the covariance matrix itself.
