"Outstanding introductory to advanced R book" - by falling in love with R on 22-DEC-2011
Reviewer Rating:
Norman Matloff has done an outstanding job explaining R in this book.  I've read it after having used R for about 2 years and feeling that something was still missing and I don't fully understand some of the deeper aspects of the language. This book has made me a much better R programmer.

The book is both broad in its coverage of various language constructs and data structures, and deep and comprehensive in explaining them.  It provides working examples, and iluminates the R philosophy: a clean functional language with strong vector operation support, and a "do more with less typing" foundation that can make programs an order of magnitude smaller and expressive.

How can one transform a vector  into a matrix or a multi-dimensional array without a copy (reshaping)?  How can one implement perl/python/php style hashes (R lists)?  How can one clean or transform data? Do database-like operations? Avoid looping using vectorized array indexing? Visualize data?  What are S3 and the newer S4 functions?  All these questions and more are answered here in a very lucid style.

If you are just starting with the language, or if you've used it for a while but itching to get more productive in R, look no further.
