Contributing

This book has been developed in the open, and it wouldn’t be nearly as good without your contributions. There are a number of ways you can help make the book even better:

• If you don’t understand something, please let me know. Your feedback on what is confusing or hard to understand is valuable.

• If you spot a typo, feel free to edit the underlying page and send a pull request. If you’ve never done this before, the process is very easy:

  • Click the edit this page on the sidebar.

  • Make the changes using github’s in-page editor (fixing typos is perfectly adequate).

  • Include a brief description of your changes in the area below the editor, then propose the file change. If you make significant changes, include the phrase “I assign the copyright of this contribution to Hadley Wickham” - I need this so I can publish the printed book.

  • Create a pull request.
