OK, I think I see the problem.? Rather than setting method="nAGQ" I need nAGQ=1.? Doing so throws the following error:
"Warning messages:
1: glm.fit: algorithm did not converge
2: In mer_finalize(ans) : gr cannot be computed at initial par (65)
Error in diag(vcov(fitmodel)) :
? error in evaluating the argument 'x' in selecting a method for function 'diag': Error in asMethod(object) : matrix is not symmetric [1,2]"
I need some help interpreting and debugging this.? One thing that I suspect is that there is a column of zeroes in the design matrix, but I'm not sure.? Any other possibilities here and how can I diagnose?

Never mind-I fixed it.
My script is throwing the following error:
"Error in glmer(formula = modelformula, data = data, family = binomial(link = logit),? :
? Argument ?method? is deprecated.
Use ?nAGQ? to choose AGQ.? PQL is not available."
I remember hearing somewhere that PQL is no longer available on lme4 but I have AGQ specified.???
Here's the line that fits my model:
(fitmodel <- lmer(modelformula,data,family=binomial(link=logit),method="AGQ"))
If I change it to nAGQ I still get an error.
Any ideas as to what's going on?
?

I'm getting the following error in a script: "Error: could not find function "lmer."??? I'm wondering of my lme4 package is installed incorrectly.? Can someone tell me the installation procedure?? I looked at the support docs but couldn't translate that into anything that would work.
