You must use the new style and call lmer when using package lme4 now. There is no full documentation on lmer yet since package lme4 is work in progress, but there are a few examples in the MEMSS package. However, I would suggest that for the rather simple model, you better don't load lme4 and Matrix, and use well-documented package nlme instead.
