Currently, the following generates an exception:
>>> s = ri.SexpVector([1, 2, 3, 4], ri.INTSXP)
>>> s.do_slot_assign("dim", ri.SexpVector([2, 2], ri.INTSXP)The issue is that s has no "dim" attribute to start off with, and do_slot_assign's implementation checks R_has_slot and errors out if it returns false. However, there is no reason to do this; the actual SET_SLOT call that rpy2 issues does the correct thing whether or not the slot already exists (it ends up calling exactly the same function as R's own dim<- operator, in fact). The attached patch removes the offending check. Built and tested. -- Nathaniel
