Using Ubuntu 9.04 and R 2.8.1.

For a project I need to use the Zelig package, which in turn wants to
use the lme4 package. When trying to use Zelig and it tries to its

packages I get the following error message.

Error in dyn.load(file, DLLpath = DLLpath, ...) :
    function 'cholmod_start' not provided by package 'Matrix'
Error in loadModelDeps(model) :
    This model depends on package "lme4". Please install this package and
try again



Looks like a version mismatch. It's probably easiest if you update to R
2.10.1 and try again; you will have to reinstall all your packages, because
of the change help format in 2.9.x

Ok, I'll give this a try (probably not a bad idea to be more up-to-date.
Hopefully that will make the problem go away.

Thanks,
Esmail
