You have to explicitly write lme4:::sigma(model) because in this version of lme4 "sigma" is hidden within the package namespace. (The triple colon is S4 magic for extracting an otherwise hidden function from a namespace.) Ben

Thanks for the suggestion. But when I try sigma(model), I get this error message: could not find function "sigma". Any other thoughts? Thanks! nola Ben Bolker wrote:
Your mileage may vary, but I have found lme4:::sigma(model) to be a reasonably reliable way to get it. Ben Bolker Nola Stephens wrote:
Hi, When using earlier version of R (2.6.2), I got a scale factor for an lmer model (where family=binomial). But after downloading R version 2.8.1, I'm unable to find this value. I'd really appreciate some advice on how to find this. Thanks! nola
