Moving from sourceCpp to a package w/Rcpp

Question

I currently have a .cpp file that I can compile using sourceCpp(). As expected the corresponding R function is created and the code works as expect

Answer 1

You are missing the forest for the trees.

sourceCpp() is a recent function; it is part of what we call "Rcpp attributes" which has its own vignette (with the same title, in the package, on my website, and on CRAN) which you may want to read. It among other things details how to turn something you compiled and run using sourceCpp() into a package. Which is what you want.

Randomly jumping between documentation won't help you, and at the end of the genuine source documentation by package authors may be preferable. Or to put a different spin on it: you are using a new feature but old documentation that doesn't reflect it. Try to write a basic package with Rcpp, ie come to it from the other end as well.

Lastly, there is a mailing list...
