   We should add a right = TRUE argument, like with cut().

   The right argument is handled like this: cut(..., right = identical(breaks, "inclusive")).

   Rename split to method?

   split currently also accept a numeric vector with values that define the splits, thus, I'd say a method argument is not fully appropriate?

   Current behavior is to return an integer vector. To be consistent with cut(), and to be safer to use, I think this function should return by default a factor - possible an ordered factor.

   Not for factors, only for numerics. When you use the labels argument, a factor is always returned.
