	I would like to compare the performance of Principal component method and
principal axis method with maximum-likelihood because my data is not
multivariate Normal.
	Besides, how can I have the communalities with 'factanal' function? I
didn't find it on html help.
	Sorry, I am a new R user...

Why do you want to use an inferior method?  And which outdated method
do you want to use?
