Garrett's book is exactly what I was looking for. Having some background in other languages, including some C++ and having just gone through Learning Python, I needed to get up to speed on R. The book is concise and well structured. Full Review >

In short, it is fun, fun to read! Every chapter or exercise is full of tasteful, useful insight as the author takes you thru accomplishing several very engaging projects. You will learn a wealth of not so obvious techniques which will help you build better performing, more accurate apps, faster working code with fewer bugs and jump with you into some under-explored areas or R.
I like the part on vectorization the most, and even tried to change my code to doing it,but it is still a work in progress as I can't QA my change to my liking. The other parts of the book that I liked and trust will be of help to most readers are working with data-frames, matrices, vectors,lists, also environments (did not see this covered anywhere else).
S3/4 and ref classes were, and largely remain obscure after reading this book. The plotting was hardly covered. Pity, it is such an in-demand topic.Integration with other languages is not there, too.
So, there is room for more improvement, nevertheless, the book I foresee will spark more interest in exploring R further.
The bottom line is,the book can serve as an additional or supplementary material and inspire more reading.
I am giving this book four stars out of five.
