[R] package installtion

I believe the problem is a column of zeroes in my x matrix. I have tried the suggestions in the documentation,
so now to try to confirm the probelm I'd like to run debug. Here's where I think the problem is:
###~~~~~~~~~~ Fitting the model using lmer funtion ~~~~~~~~~~###
(fitmodel <- lmer(modelformula,data,family=binomial(link=logit),nAGQ=1))
I added the mtrace to catch the error, but get the following:
Error in mtrace(fitmodel) : Can't find fitmodel
How can I debug this?

This is the ``push every possible button until you get a result and to hell with what
anything actually means'' approach to statistics. The probability of getting a
*meaningful* result from this approach is close to zero.
Why don't you try to *understand* what is going on, rather than wildly throwing
every possible piece of software at the problem until one such piece runs?
