[R-sig-ME] Converting lme4 model syntax into corresponding regression equation

[Ben Bolker]

   Assuming this is also you:

  If you're going to cross-post, **please** indicate that fact by 
providing a link in one or both directions!  (The info page for the 
mailing list does say: "Please refrain from cross-posting to related 
venues (e.g. StackExchange sites and other R mailing lists.)")

   The reason for this request is that cross-posting can lead to a lot 
of confusion and duplicated effort.

   cheers
    Ben Bolker
