[Rcpp-devel] changing a "const" argument

[Ramon Diaz-Uriarte]

Dear All,

I thought something like this would fail (would not compile):


// [[Rcpp::export]]
double changeAVector(const NumericVector a) {
  a[0] = 3.0;
  return 44.0;
}



But it does compile OK, and it really does modify the argument:

d1 <- c(93, 99); changeAVector(d1); d1


Is this expected?


Thanks,


R.
