Can you restate your problem a little differently? I don't quite understand what you are trying to do, and what is not working. What do you mean by "define the Rcpp::Rostream" ? You would not have to include that explicitly as our header structure already does it. See the example blog post from a few months ago: http://dirk.eddelbuettel.com/blog/2012/02/18#rcout_armadillo_example That works the same way with Rcpp alone: R> library(inline) R> R> fun <- cxxfunction(signature(), plugin="Rcpp", body=' + Rcpp::Rcout << "Hello, world" << std::endl; + ') R> R> cat("Before Rcpp-created function\n") Before Rcpp-created function R> fun() Hello, world NULL R> cat("After Rcpp-created function\n") After Rcpp-created function R> R> That doesn't work so impressively with inline etc as we come back to the prompt anyway, but by using Rcpp::Rcout all your stdout access from C++ is passed through the output stream controlled by R thanks to the work Jelmer did. Or did I misunderstand and you wanted to do something different ?
