Greetings, I am new to Rcpp, RInside and the entire family of related packages. I am experienced with R and also C++ using Eigen but I have never combined the two before. I would like to create a matrix using R and then play with it using Eigen. From what I have read so far, it seems like I can use RInside to create an Rcpp::NumericMatrix.
My question is this: to transform a matrix from a Rcpp::NumericMatrix to an Eigen MatrixXd, do I use RcppEigen? Or is RcppEigen only for calling C++/Eigen from R and not the other way around? Thanks, Stephen
