It seems that R_do_slot_assign can change the type of an S4 class slot.
For example I have a class
setClass("ostream", representation(id = "integer", keepOpen =
and inside a C-function I was able to assign a RAW vector to the id
slot. Is this intentional? I remember reading somewhere that the slot
type is guaranteed by R. Maybe this doesn't extend to C code?
Now, in the above example I actually don't know the eventual type of the
'id' slot, it will be set up in some C code that intializes the class
instance. What is the right way to define the representation in such a
