R Packages (2e)

Learn how to create a package, the fundamental unit of shareable, reusable, and reproducible R code.

Welcome!

Welcome to the online version of the 2nd edition of “R Packages” by Hadley Wickham and Jennifer Bryan. 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 book 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.
