Dear Douglas,

Reinstalling lme4 from R-forge after removing it from the harddisk
worked.

Thank you,

Thierry

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.

The combination of some data and an aching desire for an answer does not

data.

The issue is a bit more subtle than that.  You need to reinstall the
lme4 package after changing the version of the Matrix package.
There is a change in the internal code in the Matrix package between
-16 and -17.  The -16 version requires two versions of every function
in the CHOLMOD, AMD and COLAMD libraries whereas the -17 version is
back to only one version.  However, lme4 must be reinstalled (in
particular, the C code must be recompiled) after a change in the
Matrix package.
