[R] fitting a confined mixture model

[Giovanni Luca Ciampaglia]

Hello all,
I would like to fit a mixture model whose components are normal 
distributions confined in a closed interval. Since there are already 
several packages for EM, I would like to extend one of these instead of 
writing a new script from scratch. What would be the best way to 
customize such an existing package for doing that? Which one is the best 
in terms of extensibility? (e.g mixtools, flexmix ..)
