Error message

Here's the info Michael Weylandt requested:

installed.packages()[c("lme4","nlme","Matrix"),c(2,3,12)]

?????? LibPath?????????????????? Version?????? Built?? 
lme4?? "/usr/lib/R/site-library" "0.999375-40" "2.13.1"
nlme?? "/usr/lib/R/library"????? "3.1-104"???? "2.15.0"
Matrix "/usr/lib/R/library" ?????"1.0-6"?????? "2.15.0"

Looks like I have lme4 for version 2.13 rather than 2.15.? Am
I reading this right?? I didn't install this and I'm not a Linux
person so someone will have to tell me the command to 
obtain the Linux information requested.? Then maybe I can
figure whether to go to the Debian board or not.

Subject: Re: [R] Error message

I suddenly started getting the error message below.
Not sure why.? If I type intalled.packages() it
shows Matrix and lme4 installed.? Can someone tell
what's going on and what I need to do to remedy the
problem?? I'm running on a Linux box.
? ? ? ? ? ? Loading required package: Matrix
Loading required package: lattice
Error in dyn.load(file, DLLpath = DLLpath, ...) :
? ? function 'cholmod_l_start' not provided by package 'Matrix'
Error: package/namespace load failed for ?lme4?
Error: package/namespace load failed for ?lme4?

I would guess you are using incompatible versions.? Is R up to date?? are both Matrix and lme4 up to date?

(If you posted sessionInfo() we'd know this...)
