Mastering Regular Expressions, Third Edition

I have had occasion to require regular expressions in my code and it has always been a matter of trial and error, or looking online for something that should work. Some books have a chapter dedicated to regular expressions but I have always found them confusing. Enter Jeffrey Friedl and this excellent text. This man is a superb teacher. He not only explains well but also preempts every doubt I could have as I read his work. His examples are thorough. My only hope is that he writes other books.

Presented as a spatial mashup, this tutorial introduces the user to R packages, R syntax, and data structures. The user will learn how the R environment works with R packages as well as its own capabilities in statistical analysis. We will be accessing spatial data in several formats-html, xml, shapefiles, and text-locally and over the web to produce a map of home foreclosure auctions and perform statistical analysis on these events. chapter 1.
