Latent Class Analyisis in R

Hi,

I am new to R. I would like to know if there is a package available that
will estimate a 2-class Latent Class Analysis, with trichotomous
observed variables, some of which are free to covary.  

I have read the PDF files regarding the e1071 and gllm packages, but it
appears that these only allow dichotomous measured variables, and it is
not clear to me whether they allow the measured variables to covary.

Thanks!
