As Dieter points out, this is likely a mismatch between the versions of the lme4 and the Matrix packages, which are very closely linked together. It appears that the version of the lme4 package is too old for the version of the Matrix package, which is hard to catch in the dependencies (lme4 depends on Matrix but not the other way around). As Dieter suggests, it would be best to install the most recent version of R which can then pull in the most recent versions of the lme4 and Matrix packages.
Hi, Yes, you were both right on the money. I took your suggestion and upgraded R to 2.10.1 and I had to install lme4 and zelig from source to get the current packages. Thanks again!
