See this page. We're not done with them all but chapter 3 and 4 are there and the regression chapters are not too far behind.
The Rnw files (using knitr LaTeX) are there along with the corresponding pdf files.
You may have better solutions than we have here and we would love to see them. You can do so by creating a pull request or, if you are not git-savvy, drop an email to Max (max.kuhn@pfizer.com) and/or Kjell (kjell@arboranalytics.com).
