I'm trying to estimate a multinomial logit model but in some choices only alternatives from a subset of all possible alternatives can be chosen. At the moment I get around it by creating "dummy" variables to mean the alternative is not available and let it estimate this coefficient as highly negative. Is there a better way to do it?

...? Either way, I think the mlogit package would be inappropriate for you. I imagine you would have much better luck using MCMCpack or writing a model with rstan or something Bayesian. Unless I'm missing something.
