Notes from reading through R Packages by Hadley Wickham. This is meant to review, not replace, a thorough readthrough. I mainly wrote this as a personal review, since writing summaries and attempting to teach others are some of the best ways to learn things.

Introduction

• Packages are used to organize code together so that it can be used repeatedly and shared with others.

• A lot of work with packages is done via the devtools package.
