[Rcpp-devel] Rcpp compile question

[Henry Bee]

Hi Dirk,

I've been developing with R for the past year and came across your wonderful
presentation slides on Rcpp a few months ago. I am now turning to your Rcpp
package to translate the slowest portion of my code to C/C++.

I am testing the first example provided on page 6 in
your Rcpp-introduction.pdf document. Unfortunately I am getting compile
errors (listed below). Could you provide some guidance?

Kind regards,

Henry
