[R] lme4 error after Matrix update

[ONKELINX, Thierry]

Dear Rüdiger,

Try to uninstall AND fysically remove (delete) lme4 and Matrix from the harddisk. Then installing them again should do this trick. At least it did on my laptop.

HTH,

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.

Onderwerp: [R] lme4 error after Matrix update

Dear all,

after recently updating my R-packages I am unable to work with lme4, 
since it does not load. What I get is this:

Error in inDL(x, as.logical(local), as.logical(now), ...) :
   function 'cholmod_l_start' not provided by package 'Matrix'
In addition: Warning messages:
1: package 'lme4' was built under R version 2.8.1
2: package 'lattice' was built under R version 2.8.1
Error: package/namespace load failed for 'lme4'

Various trials to remove and reinstall the Matrix and lme4 packages were 
unsuccessful.

I am working on Windows XP, R-version 2.8.0:

 > sessionInfo()
R version 2.8.0 Patched (2008-10-21 r46769)
i386-pc-mingw32

Any help greatly appreciated.
