[R] Error computing mlogit model

[Jim Lemon]

Hi Eric,
There are a few mysteries in your request. As we don't know what "des"
is, it is difficult to see why it does not have the correct number of
dimensions. It looks like it should be an n x 6 matrix, but is that
what it really is and does the mlogit function expect such a matrix?
