R help - Oct 2002 - Identification of heterogeneous subpopulation (MECOSA3)

Hi,

i read something about MECOSA3 (G.Arminger)
which is a software to :
"Analysis of finite mixtures of conditional Lisrel models"

I'm very interested to identify heterogeneous subpopulations and ask
me are similar functions doing something in R, too ???

I know SEM and perhaps with some additions/modifications it is possible
doing this general mean- and covariance structures with metric and
non-metric dependent variables and mixtures of conditional multivariate
normal distributed variables ?

...but until now i'm not a expert for this and must train myself to
understand
the  mathematical purposes and intentions from this apporach.

Neverthless it would be nice when an expert for this have some
R  related suggestions for me i.e. working with special packages/functions
as a starting point !


Thanks for advance and regards,
Christian
