lme4 is S4 package.So you should use slotNames to see what slots an object has,and use @ instead of $ to extract the slot you want.
library(lme4)

2006/7/15, A.R. Criswell <[EMAIL PROTECTED]>:
Hello All, I would like to retrieve some of the results from the lmer(...) function in library lme4. If I run a model, say fm.1 <- lmer(y ~ 1 + (1 | x), data = dog) and try names(fm.1), I get NULL. Is there anyway to retrieve the information?
