[R] Efficient multinom probs

Dear R-helpers,

I need to compute probabilties of multinomial observations, eg by doing the following:


However, my question is whether this is the most efficient way to do this. In the call prob[,y] a whole matrix is computed which seems a bit of a waste.

Is there maybe a vectorized version of dmultinom which does this?

Best, Ingmar
