Package development

Packages are the fundamental unit 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, but start with the basics and then improve it over time. It doesn't matter if your first version isn't perfect as long as the next version is better.

• Philosophy
• Package basics
• Development
• Documentation at both the function and package levels
• Testing
• Good code style
• Namespaces, to minimise conflict with other packages
• Source code control: git + github
• Ready for release
