[R] Error in Rcpp/inline (Windows XP)

[allenhahaha]

Hi, everyone,

I am just trying to use Rcpp in my computer, and I would like to try a
simple example from website, but R keeps reporting me error. I am using
Windows XP, and has installed Rtools and GSI.

Here is the response: 

> src = '
+ Rcpp::NumericVector xa(a);
+ Rcpp::NumericVector xb(b);
+ int n_xa = xa.size();
+ int n_xb = xb.size();
+  
+ Rcpp::NumericVector xab(n_xa + n_xb - 1);
+ 
+ for (int i = 0; i < n_xa; i++)
+   for (int j = 0; j < n_xb; j++)
+     xab[i + j] += xa[i] * xb[j];
+  
+ return xab;

Also, here is a test by Romain that perhaps useful.
