Rcpp gives you the tools, but it is up to you to use them.

Sooner or later, everything in R ends up in C or fortran.

An R formula is not much more than a language object, so you can
manipulate it through the Rcpp::Language class. If you have ideas,
design thoughts, on how to make it more convenient we will listen.
