Hey John, thanks for making me notice that document - I just skipped over it the past hour and I think I like that very condensed If you want to do this ->it works like that approach. Besides that I had the impression, though that it's content - while more strongly condensed - is basically not too different from what is covered in R for Stata Users by the same author (and his co-author), which I already have. But I might be wrong, so in case you should know both books: would you think the R for SPSS/SAS-book will provide a lot of additional info given that I have the R for Stata already or will they more or less overlap?
