"Are you using data=myframe in the glm call? Otherwise, you're open to masking by variables in your workspace."
FYI, the data statement doesn't seem to be the shortcut it is elsewhere when the form of the argument is glm(cbind(success,failure)~predictor, family=binomial, data=myframe). The data statement doesn't seem to put 'myframe' in the environment where cbind operates. Choices for the user are to fully quality names inside of cbind [i.e., cbind(myframe$success,myframe$failure)] or to attach 'myframe' to the working environment. The same thing happens in lmer.
