Or change the first line from NumericMatrix to: Rcpp::IntegerMatrix r_m(mem); Then the behaviour is reversed. The matrix of doubles does not get modified, but the matrix of ints does! Dirk, Romain, this is a bug-in-waiting. Is there any way to generate a warning when the implicit deep copy happens? Or alternatively when the pointer is being used implicitly... but my hunch is that I want to know when there is any implicit conversion between int and double: modern C++ style is to explicitly declare all type conversions with static_cast<> and friends.
