[R] lme4 package and importIntoEnv errors

[Patrick Connolly]

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.

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?
