search for: r_do_slot_assign

Hi, 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 = "logical")) and inside a C-function I was able to assign a RAW vector to the id slot. Is this intentional? I remember reading somewhere...

...a fresh checkout of the development branch. $ svn up At revision 44759. $ grep -i has_slot `find include -name '*.h'` $ grep -i _slot `find include -name '*.h'` include/Rdefines.h:#define GET_SLOT(x, what) R_do_slot(x, what) include/Rdefines.h:#define SET_SLOT(x, what, value) R_do_slot_assign(x, what, value) include/Rinternals.h:SEXP R_do_slot(SEXP obj, SEXP name); include/Rinternals.h:SEXP R_do_slot_assign(SEXP obj, SEXP name, SEXP value); ..or did I miss it ? Thanks, L.
