[R-SIG-Mac] Latent class analysis issue

[Byron Ellis]

R-help would probably be a better place for answers to your question
(this isn't a Mac specific problem), but at a guess the number of
variables you've specified isn't the same as the number in your
example. Though, I've never used e1071's LCA function (didn't even
know they existed until just now) so I'm not positive.
