Hello, I' doing some simulation on (confirmatory) factor analysis on a covariance matrix and I resort to factanal() function, which works fine but it performs only the maximum-likelihood method of extracting factors. I wonder if (and where) I can find a package that performs the principal axis factor (PAF) procedure for extracting factors. Thanks in advance to all, ennio.
