Thanks again David. Looking again I now see the last line of the Acknowledgements which directs the reader to the author's website to get the datafiles. Of all the places I thought to look I had never considered reading the Acknowlegements! It seems to be that moving it about one line farther in the book - into the "Getting Started" chapter - would have been a better idea! Oh well, I have highlighted the website for future users of my copy!
