Answering my own question here as I figured it out.

R mlogit can't handle when none of the alternatives in a choice set is selected. R also needs the data ordered properly, each alternative in a choice set must be in a row. I hadn't done that due to some data management. Interestingly, Stata can handle both of these conditions, so that's why my Stata commands worked.

As an aside, for those interested, Stata's asclogit and R's mlogit give the exact same results. Always nice when that happens.
