Rf_defineVar(symbol, R_UnboundValue, environment) questions
...nt)
to [sort of] remove 'symbol' from 'environment'
Using it makes the R-level functions objects(), exists(), and get()
somewhat inconsistent and I was wondering if that was intended. E.g., use
SHLIB to make something from the following C code that dyn.load can load
into R
% cat defineVarAsUnboundValue.c
#include <R.h>
#include <Rinternals.h>
SEXP defineVarAsUnboundValue(SEXP name, SEXP envir)
{
Rf_defineVar(name, R_UnboundValue, envir);
return R_NilValue;
}
