The biggest collection of R books (and maybe later some other resources too)

Please feel free to contribute paid and free books - see the github.

The format for adding book entries is:

## [Name of book]

[Author] -link to twitter bio / blog

[Brief description of content]

Note if its a paid product and approximatley how much

(link to book)

Sometimes it's difficult to know in which chapter to place it, but I default to using either the name of the book as a guide, the first bit of how the book describes itself or failing that, what I think it should be. It's okay to add a book to more than one section if you feel it strongly fits both.

Feel free to add both free and paid books - just note which books are a paid resource.
