Is it possible to define an external special function (SPECIALSXP)? I'm trying to do some language-level work, and don't want my arguments evaluated before they hit C.
It looks like the only way to define a SPECIALSXP is by using XX0 in the `eval' field of R_FunTab; is there any way to make this applicable to externally defined functions? ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
