Acknowledgments

No book is the product of a single person. There are many people who helped make this book possible, directly and indirectly. I'd like to thank the R community for creating R and for fostering a dynamic ecosystem around it. Thanks to Hadley Wickham for creating the software that this book revolves around, for pointing O'Reilly in my direction when they were considering a book about R graphics, and for opening up many opportunities for me to deepen my knowledge of R.

Thanks to the technical reviewers for this book: Paul Teetor, Hadley Wickham, Dennis Murphy, and Erik Iverson. Their depth of knowledge and attention to detail has greatly improved this book. I'd like to thank the editors at O'Reilly who have shepherded this book along: Mike Loukides, for guiding me through the early stages, and Courtney Nash, for pulling me through to the end. I also owe a big thanks to Holly Bauer and the rest of the production team at O'Reilly, for putting up with many last-minute edits, and for handling the unusual features of this book.
