Thanks for giving us feedback on the book. Please follow these guidelines:

Please state the version of the book by referencing the version and date on the book's first page (under the title and authors).

Please tell us where exactly the issue is (e.g. chapter, section, figure number, etc.) and, whenever possible, copy/paste the text in question using > in the issue. For example:

Since the repo and data are publicly available, it should be entirely possible to create a minimal reprex (reproducible example).

The goal of a reprex is to make it as easy as possible for me to recreate your problem so that I can fix it: please help me help you!

If you've never heard of a reprex before, start by reading "What is a reprex", and follow the advice further down that page.
