[R] Factor Analysis functions...

[Chris Bergstresser]

Hi all --

     I'm running a Factor Analysis on my dataset, and I've located the 
"factanal()" and "princomp()" methods.  I don't want to do a PCA, so it 
looks like I should use factanal(), but factanal() requires specifying 
the number of factors you expect from the analysis.
    Are there any packages out there explicitly for Exploratory Factor 
Analysis that do not require specifying the number of expected factors?
