Extending Rcpp

Abstract

This note provides an overview of the steps programmers should follow to extend Rcpp (Eddelbuettel, François, Allaire, Ushey, Kou, Chambers, and Bates, 2016a; Eddelbuettel and François, 2011) for use with their own classes. This document is based on our experience in extending Rcpp to work with the Armadillo (Sanderson, 2010) classes, available in the separate package RcppArmadillo (Eddelbuettel, François, and Bates, 2016b). This document assumes knowledge of Rcpp as well as some knowledge of C++ templates (Abrahams and Gurtovoy, 2004).
