[Rcpp-devel] RInside constructor calls srand

Hi Dirk:

Thanks for the quick reply.

Also, RInside embeds R. And just as in normal R, if you want reproducibility
from the embedded R provided by RInside, you need set.seed(). Just use it.

I tried something like this:

#include <stdlib.h>
#include <iostream>
#include <Rcpp.h>
#include <RInside.h>

using namespace std;

int main() {
	srand(1);
	RInside r(0, NULL);
	r.parseEvalQ("set.seed(0)");
	cout << rand() << endl;
	return 0;
}

But every time I run the program, I get a different random number. Am
I missing something?
