[ONKELINX, Thierry]

Dear Georgina,

Have to tried to run your code in a fresh session? Can you provide a reproducible example of your problem and the output of sessionInfo()?

To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.

The combination of some data and an aching desire for an answer does not ensure that a reasonable answer can be extracted from a given body of data.

Dear list,

I am using the lme4 package on R studio (v.0.98.994)****. I haven't used it in a while but I have been regularly updating my packages.  Recently I attempted to run a simple mixed model:>
lmer(mean.perDay~complexity+(1|regime),data) and I get the following error message:

Error in get(name, envir = asNamespace(pkg), inherits = FALSE) :
   object '.setDummyField' not found


My question is, has anyone else faced any difficulty using lmer and if so can you advise me on how to fix my problem?  I am a PC (windows 7) user.

Thanks,

Georgina
