Hello, For the BUILTINSXP and SPECIALSXP types, the R Internals page documents "An integer giving the offset into the table of primitives/.Internals. " What macro gives me the value of this integer? I guess something like this would work had R_USEINTERNALS been defined v->u.primsxp.offset (where v is a SEXP of either of the above types). What is the portable version? Thank you Saptarshi
Access to integer value of BUILTINSXP/SPECIALSXP

After some reading, what i really need is something to give access to PRIMNAME(obj). Setting #define R_USEINTERNALS doesn't work and i'd rather not use internals. Is the some exposed api call to get PRIMNAME? Thank you Saptarshi On Sat, Sep 12, 2009 at 2:08 PM, Saptarshi Guha
