[R] multivariate splits

If by "multivariate split" the OP meant splitting on combinations of
covariates (instead of multi-way split on a single covariate at a time),
there aren't that many methods published (AFAIK).  All the ones I know about
are in the cheminformatics area:  RP-SA and generalizations/extensions of
it.  No R package I know of can do it.

Best,
Andy
