Here's another (non-R) option to explore:

It's been a while since I looked at it.  IIRC, the coding is a bit awkward (e.g., instead of using macro arguments, users must modify values in the macro definition).  But I think the results it generates are probably okay.

The same authors have also recently published SPSS syntax to compute polychoric correlations, by the way.

Hi Jon Peck and all,
Where can I download your R Extension Command that performs EFA based on Tetrachoric correlation coefficients? I will use it to perform EFA for my dichotomous variables.
Or are there SPSS macros available?
Thank you.Eins
