The C++ code in my package has using namespace Eigen; but this doesn't get put at the top of the auto-generated RcppExports.cpp. As a result compilation fails complaining MatrixXd etc is not recognized. I can manually add using namespace Eigen; to RcppExports.cpp and everything works fine, but this make the workflow pretty painful.

Is there some way to configure Rcpp to automatically add using namespace Eigen; to RcppExports.cpp?

  For interfaces like function signatures I recommend to fully qualify and use e.g. Eigen::MatrixXd. Look what other packages do. Also, see the Rcpp Attributes vignette about the mypackage_types.h header (where mypackage gets replaced with your package name).

  Thanks Dirk, mypackage_types.h is exactly what I want.

  Also, note that in general, using namespace foo can lead to headaches down the road. See c++- Why is "using namespace std" considered bad practice?
