Subject: [Rd] `extends()'at C-level?
Message-ID: <Pine.LNX.4.51.0404021120360.15532@artemis.imbe.med.uni-erlangen.de>



One can check easily if an object is of class "foo" via

   strcmp(CHAR(asChar(GET_CLASS(obj))), "foo")

and I wonder if there is high-level functionality to check
if `obj' extends a class?

Best,

Torsten
