Thanks Martin,
R --vanilla did the trick.
By the way, is there a way to check which version of a lme4
or Matrix I am using in a certain instance of R?
We are running multiple versions of R on the same server
until we are sure all our operational code is behaving well
under a new version of R or of a package.
Now I start doubting if we ever have been testing what we
were intendng to test...

Hi Joris,
I suspect you somehow load an older version lme4 or Matrix than you
think you are loading.
Or then you have an lmer() function or a class definition {from a
saved workspace ????} in your work space.
example(lmer) *must* run correctly for the 'lme4' package
CRAN at all, hence it must be unique to your setup.
Maybe as a first step,
run R as "R --vanilla" ?
