Rcpp is a package that enables you to implement R functions in C++. It is easy to use even without deep knowledge of C++, because it is implemented so as to write your C++ code in a style similar to R. And Rcpp does not sacrifice execution speed for the ease of use, anyone can get high performance outcome.

This document focuses on providing necessary information to users who are not familiar with C++. Therefore, in some cases, I explain usage of Rcpp conceptually rather than describing accurately from the viewpoint of C++, so that I hope readers can easily understand it.

I would greatly appreciate it if you kindly give me any feedback on this document.
