We are probably going to include a check in the next Rcpp release which calls
messages()whenR.his included beforeRcpp.h(orRcppArmadillo.h). This can lead to side-effects regarding things like 'strict headers',Rf_*prefixing and alike. Your package (for which I had a local fork so it came up whengrep'ed around) was not affected and there is no need for immediate action, but just as you removed the#include "R.h"fromfastLars.cppbefore I could nag ... we still have one incorHuber.cpp. (Edit: Oh it tricked me.
