Hi Josh, Thank you for your feedback, after lot of trial and error the problem is finally solved. To solve this problem, I tried in this order: 1) uninstalling the two packages "Matrix" and "lme4" and reinstalling them. 2) uninstalling doBy and reinstalling it with and without 1) 3) upgrading to the latest R version and re-doing 1) 2) And finally 4) wiped all R traces from my Mac OS X 10.7.2 and re-installed the latest version. The latest Matrix version seems to have changed in the meanwhile so I was lucky and now it works. It seems to me that the whole concept of dependency analysis for installing packages in R is broken ... seems like the packages depend only on the package name and not on the specific versions which is wrong as in this case, chances are that a user will say in this "live lock" where will never find a "happy together" versions of Matrix and lme4 ... but well, you statisticians know better about chances :P
Version information can be incorporated. For example, note the imports line of the zoo DESCRIPTION file where it specifies a specific version or later of lattice: https://r-forge.r-project.org/scm/viewvc.php/pkg/zoo/DESCRIPTION?view=markup&root=zoo
