[Rcpp-devel] Are there any C++ function name restrictions?

Since you changed the function name, you can no longer call rcpp_hello_world() from R. Try calling the new function name.

Better yet, start over, leave rcpp_hello_world code alone and add another .cpp, .h, and .R file with another function.
