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

In short, the trick is to call compileAttributes() from within the root of the package. So for instance for package foo

$ cd /path/to/foo
$ ls
DESCRIPTION  man  NAMESPACE  R  src
$ R
R> compileAttributes()

This command will generate the RcppExports.cpp and RcppExports.R that were missing.
