Best R book for programmers

I found R Cookbook very useful http://shop.oreilly.com/product/9780596809164.do A lot of examples, easy to get the R language structure esp. when you already know other languages.

The best book to be productive in R quickly is "Applied Predictive Modeling" by Max Kuhn and Kjell Johnson. The best book on programming in R is "The Art of R Programming" by Norman Matloff.

Here is a post that has a list of books. There is an R book mentioned above the code which is good. Yet another excellent resource are forums like stackoverflow, but the process of learning can be slow. There is of course the cran project site itself here but again its not in an easy readable format the book offers. Hope that helps

There is a book called "Machine Learning for Hackers"

Here it's abstract:

If you’re an experienced programmer interested in crunching data, this book will get you started with machine learning—a toolkit of algorithms that enables computers to train themselves to automate useful tasks. Authors Drew Conway and John Myles White help you understand machine learning and statistics tools through a series of hands-on case studies, instead of a traditional math-heavy presentation.

Each chapter focuses on a specific problem in machine learning, such as classification, prediction, optimization, and recommendation. Using the R programming language, you’ll learn how to analyze sample datasets and write simple machine learning algorithms. Machine Learning for Hackers is ideal for programmers from any background, including business, government, and academic research.
