[R] constraining betas with mlogit package

[Bert Gunter]

I don't know the answer in general, but for the specific constraint of
two coefficients being the same, I would assume that you should create
a new covariate which is the sum of the two individual ones and fit
this single combined covariate instead of the two separate ones.

Cheers,
Bert
