Hi,
I'm wondering if this code from the "Writing R Extensions" manual
is really safe:
SEXP mkans(double x)
{
SEXP ans;

Hi,
I'm wondering if this code from the "Writing R Extensions" manual
is really safe:
SEXP mkans(double x)
{
SEXP ans;
PROTECT(ans = allocVector(REALSXP, 1));
REAL(ans)[0] = x;
UNPROTECT(1);
return ans;
}
double feval(double x, SEX
