Dear Georgina, Please the mailing list in cc. Someone else might join the discussion. sessionInfo() gives all loaded packages and their version. That helps to see which versions you used. Your code seems OK. So if it works in a clean session (try stand-alone R as well), then the data object might be the culprit. It's hard to diagnose the problem without it. See http://adv-r.had.co.nz/Reproducibility.html for more info on how to make a reproducible example. Note that it doesn't have to be the actual dataset. A dummy dataset that replicates the problem is OK. Best regards, ir.

This is the first time I've emailed a group with an R problem and so I've never had to forward and examples of my data. For this reason can you tell me exactly what I need to send you for it to be a reproducible example? Thanks, Georgina

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()? Best regards, ir.

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.
