This book is meant to be a free, central reference for developers of R packages accessing web resources, to help them have a faster and more robust development. Our aim is to develop an useful guidance to go with the great recent tools that vcr, webmockr, httptest and presser are.
The ultimate goal of this book is to teach you how to create a relatively simple R package based on the so-called S3 classes.

Packages are the fundamental units of reproducible R code. They include reusable R functions, the documentation that describes how to use them, and sample data. In this section you’ll learn how to turn your code into packages that others can easily download and use. Writing a package can seem overwhelming at first. So start with the basics and improve it over time. It doesn’t matter if your first version isn’t perfect as long as the next version is better.
