Following up on the successful “R in a Nutshell”, O'Reilly has just published a new book on R, The R Cookbook, by Paul Teetor. Here's the description:
Perform data analysis with R quickly and efficiently using the task-oriented recipes in this cookbook. The R language and environment include everything necessary to perform statistical work right out of the box, but its structure can often be difficult for beginners and experienced computer geeks alike. R Cookbook offers a collection of concise recipes that will help you be productive with R immediately.
I haven't taken a look at it yet, but it's an interesting concept, and the table of contents looks like it contains useful, practical recipes for common R tasks. I'll report back when I've taken a more detailed look, but in the meantime, I'd love to hear comments from anyone that's found this book useful.
