draft of new mixed models book

I just received this email through the r-sig-mixed-models group, from Douglas Bates:

I have finally gotten the chapter drafts of the book, "lme4:
Mixed-effects Modeling with R", that I am writing to the point where I
think they can be helpful to others.  I believe I have properly
committed them to the R-forge site but they will not appear for an
hour or so.  They should be available under
http://lme4.R-forge.R-project.org/book/

Chapters 1, 2, 4 and 5 are currently available as are the .R files for
those chapters.  Chapters 4 and 5 will have material added to them.  I
don't expect to change chapters 1 and 2 until I get reviewers reports.

When pointing out errors, inconsistencies, bad writing, obtuse
explanations, etc., please be gentle.
