Comment(by josefpktd):

 Looks very nice

 xtabs drop.unused.levels mentions that the test doesn't work if a marginal
 is zero.

 I would check how it behaves in this case, and also when we have a few
 zeros in the contingency table

 It's also good to know that it is partially the equivalent of R's
 summary(xtabs(...)) and not chisq.test.
