Thanks for that explanation. I was curious to know why it's so different from other packages I've had no trouble with.

My problem did, indeed, arise from using an older version of lme4 with a new version of Matrix. Douglas's post explains why lme4_0.95-8.tar.gz is so much smaller than lme4_0.8-2.tar.gz. I feel much less confused now.

Thank you Renaud Lancelot and Deepayan Sarkar also.
