It's rare to find a book on a complex topic written in a lucid, hands-on way. This is book is one such rare work. I had no prior background in R, and always wanted a quick intro that would give me some practical footing in the language. The content in this book did the trick.
If you want to dive into the world of R, and don't know how, look no further. Just follow along (there are code repo and links in this book) and you should be in a new league within a short time..
