[R-sig-ME] env() statement

[Ben Bolker]

  I'm too busy to post all the details, but I *believe* that for people
who are struggling with the env() command in Doug Bates' book draft
code, that replacing  env(x)$y with x at re@y will in general work -- e.g.

fm1 at re@Zt rather than env(fm1)$Zt

  I'm not sure of this -- you should check the results against the PDFs
online -- but it may get you through.
