Title: The Most User-Friendly Introduction to S and S-Plus
Review: The book "An Introduction to S and S-Plus" by Phil Spector is an excellent text for anyone who wants to get things done with the S/S-Plus statistical package. The book covers the basics of loading data into the system, how to manipulate datasets using the various operators and functions of S-Plus, as well as how to make full use of the graphics subsystem. Advanced topics such as how to dynamically load object code into S are also covered. The best part of the book is that it offers very useful examples of how to do things. Unlike many other computer books, the examples aren't contrived expository devices that the author cooked up in a minute. I've found that, even after using S-Plus for many years, I come back to this book over and over again for guidance on how to get things done. I give the book my highest recommendation.
