Hi

My goal is to do a weighted (by population) factor analysis (of votes) using
R.

For that I prepared the weigthed cov matrix, which matrix I pass in the
factanal function.
I'm facing troubles in calculating the scores of a factor analysis using as
entry a cov matrix as Factanal is not able to get the scores (normal in the
case of absence of any x).

I'm looking for a method to calculate the scores "manually" afterward. Does
anybody has the way I can retrieve that?
