This is the main repository for the R Companion to Montgomery’s Design and
Analysis of Experiments (2005).

This project was started several years ago. Although it grew smoothly during
the first two years or so, it hasn’t evolved much since then. I released
minor updates from time to time. Last update is 2012-12-02.

Problem is that TeX code is clearly outdated now, and it relies on a tex -> ps -> pdf toolchain, with Python code to tangle R code and create a
pictures gallery. There are better options with XeLaTeX (which I tried
last year on this document) or lualatex (released with
TeX Live 2013). I should fix this at some
point. There are more serious issues though: Now, CRAN features many R
packages for
DoE, and I’m
afraid many code chunks should be updated to better reflect state of the
art. Lastly, I didn’t use Sweave—and I can’t remember why—,which makes
updating the whole document really painful at times.

So, here are the new development process, after I pushed everything on
GitHub:

• I will keep the old document for historical reason. It can be found in the
  archive.tar.gz tarball, without intermediate compilation files.
• The new version will be based on knitr and
  XeLateX.
• I will try to update old code using available R packages inasmuch as
  possible.
• Newer editions of Montgomery’s DAE have been published, but I will stay at
  Edition 5.
