How do I create my own library for R

I’m interested in learning R and would like to start by creating my own library to add certain statistical calculations. I’m wondering how to go about this. Has anybody been able to do this? If so, how do I go about building a library in R?


If you don’t want to use Rcpp, you can write a package with your own functions in Rcpp and use that to create your package’s source files.
For example, consider this Rcpp function I created for a few operations like means, standard deviations and covariance on a vector of numbers:
// [[Rcpp::export]] double mean(NumericMatrix x) {
Rcpp::NumericVector::iterator n = x.begin();
return n->Me
