Hello all,

R2.2.1, W2k

I posted a similar question last week after having problem with a group
update (using update.packages()), without getting any answer.

Now I have updated all packages separately, and found that the problem
comes from nlme:

Everything comes home, the md5 checksums are ok, but then the old version
can??t be removed from my computer, leaving a "nlme" library with only the
"libs" sublibrary left.

As my R doesn??t start without nlme, I am stuck here. R doesn??t start with
only the "libs" left and doesn??t start without nlme. What??s going on?

It??s no big crisis as I have the nlme version from the R installation
file, but I try to keep my installation as updated as possible, so it??s
irritating. :)

You cannot update a package if it is loaded, because Windows locks the dll.
Hence start R without loading nlme (that it is loaded might be because 
you mentioned it in some Startup file such as .Rprofile or a saved 
Workspace image loads the package for some reason - don't know whether 
this could happen for nlme).
Hence RGui --vanilla might be right for you. Then update.packages().
