An R and S Plus Companion to Applied Regression

* Various facilities of S are introduced as needed within the context of detailed examples.

* Cumulative examples: Later examples often depend upon earlier ones, but examples in separate chapters are always independent of each other.

* Asterisks note more demanding material that may be skipped without loss of continuity.

* Boxes explain and highlight the many small differences between S-PLUS and R, and between S3 and S4, so that readers can quickly locate the material that is relevant to their version of S or skip that information.

* A companion Web site features instructions for downloading, installing, and using the Windows version of R; add-on packages; versions of the car (companion to applied regression) library that includes the software and data sets described in the book; an appendix for various extensions of regression analysis not covered in the text; and downloadable scripts for all of the examples in the text.
