I've used packages for some years now and seldom had any trouble using the tgz files. Now I've come across something I've never seen before.

Loading required package: methods
Loading required package: Matrix
Loading required package: latticeExtra
Error in importIntoEnv(impenv, impnames, ns, impvars) :
        objects ��coef��, ��coef<-��, ��corMatrix��, ��matrix<-��, ��pdFactor��, ��pdMatrix�� are not exported by 'namespace:Matrix'
Error: package/namespace load failed for 'lme4'

The Matrix and latticeExtra were downloaded and installed yesterday and the methods is what came with R-2.1.0.

I notice in the archives someone had a very similar problem with version 2.0.1 and Windows in January this year, but there's no further mention that I found. That one seems to have been fixed with new Matrix and latticeExtra packages. However, I'm using newer ones already. So I thought it might have to do with 2.1.0 rebreaking something.

'CHANGES IN R VERSION 2.1.0 patched' doesn't make any mention of importIntoEnv, so I figured patching wasn't likely to make a difference. I also figured that latticeExtra is not likely to be as buggy as that.

The only thing I can think of that would be slightly non-standard about my installation is the fact that I install packages (in addition to the recommended ones) in a different place from the "normal" ones. Could that be a source of error on this system? Alternatively, is there anything I could do about this namespace business?
