WebTo use OptimLib with an R package, first generate a header-only version of the library (see above ). Then add the compiler definition USE_RCPP_ARMADILLO before including the OptimLib files: 1. 2. #define USE_RCPP_ARMADILLO. #include "optim.hpp". Or you can set this preprocessor directive during compilation: 1. g++ ... WebMatrix Multiplication Using Rcpp Package in R (Example) In this post, we show you how to do matrix multiplication using the Rcpp package in R.Rcpp helps to speed up our R code by integrating C++ code for specific code parts.
