OK, I think I see the problem. Rather than setting method="nAGQ" I need nAGQ=1. Doing so throws the following error:
Congratulations, now you understood what R meant with its message "Argument ‘method’ is deprecated."
"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,
So have you not even tried to get rid of that? Oh, come on. Uwe Ligges
but I'm not sure. Any other possibilities here and how can I diagnose? ----- Original Message ----- From: Scott Raynaud<scott.rayn...@yahoo.com> To: "r-help@r-project.org"<r-help@r-project.org> Cc: Sent: Tuesday, November 15, 2011 2:11 PM Subject: Re: package installtion 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? ----- Original Message ----- From: Scott Raynaud<scott.rayn...@yahoo.com> To: "r-help@r-project.org"<r-help@r-project.org> Cc: Sent: Tuesday, November 15, 2011 1:50 PM Subject: package installtion 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. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
