A couple of initial reactions. The location of the R.h header is platform
dependent. On what platform are you working? You can always just paste the
output of the R function "sessionInfo()".

Next, the Rcpp team strongly recommends using an "inline"-based approach
where possible and an R package when that isn't possible. Those two
approaches take care of the file/directoy linker flags for you.
