[R] Factanal fits

[lhunsicker at mchsi.com]

Many thanks to Michael Weylandt and Prof. Ripley for answers to yesterday's query.

1.  The response to 

methods(print)

is that the print.princomp method is "non-visible," not "suppressed," as I misquoted. 
The method can be located by either

getAnywhere(print.princomp)

as suggested by Michael or by 

getS3method(f = 'print', class = 'factanal')

as suggested by Prof. Ripley.  I learn something new about R every day!

2.  Prof. Ripley is correct, of course.  To print out the test whether "The test of the hypothesis that 
X factors are sufficient." when submitting a covmat, the factanal function needs to know the n.obs.  The following call, packaging n.obs with the covmat, worked perfectly:

cor3.fa1 <- factanal(factors = 6, covmat = list(cov = cor3, n.obs = 418))

Again, thanks.
