0.4 Book website
Although you can use this book as a standalone resource, we recommend you use it in conjunction with it’s companion website. The course website contains a series of exercises which will help you practice writing R code and test your understanding of key concepts - you certainly won’t learn how to use R by watching other people do it (or reading a book about it!). The website also contains solutions for each of the exercises and a plethora of links to additional tutorials and resources.
