I am having a problem extracting from "mer" objects.  
 
I have constructed my problem using existing datasets.
 
Using the following commands:
 
require(lme4)
fm1 <- lmer(Yield ~ 1 + (1 | Batch), Dyestuff)
fixef(fm1)

I get the following error message:
"Error in UseMethod("fixef") : no applicable method for "fixef""
 
I know that "fixef" is in lme4 and UseMethod is in "base", so I am stuck trying to sort out this problem.  This problem applies to all extraction commands from mer objects.
 
Any help is greatly appreciated, I am new to using R.
