copies of the programs used in the book can be found in the spuRs package for R (details of how to get this are given in Section 1.6 of the book). The package also includes a copy of the latest errata (which I have also attached).
We have solutions to some of the exercises, which we are happy to provide to instructors. I have attached an archive containing them. We will be adding more solutions in due course, but please encourage those using the text to get in touch if they have questions about particular exercises.
I also have some slides that I prepared for use with the text. I am happy to provide these to instructors, but they would have to be used with some care, as they were prepared with a particular cohort in mind, and would not be suitable for students at all levels.
