After installation of the latest version of R (2.6.0) I have a problem with
loading the nlme library. When I use RGui under Windows XP, and try to install
the nlme package, I get a warning that installation was unsuccessful due to a
previously installed version of nlme. But the nlme library does not appear on
the list of libraries that are available for loading under RGui. This happens
after a fresh install, and deletion of all R directories. Furthermore after this
unsuccessful attempt to install nlme, RGui can not be used any more. When I try
to restart it, it gives an error message about some problem with restoring
things, mentions an .Rdat file, and quits.
I next tried to use Rterm.exe (out of desperation), and it came up successfully.
Also, in this terminal session I was able to install nlme by using the
install.packages() command. And after going through these steps, RGui starts up
again normally!
I have tried this twice, starting from scratch, using R 2.6.0 and the patched
version R 2.6.0pat. In both cases the same sequence of events takes place.
So what prevents RGui from successfully installing nlme, while Rterm.exe has no
such problem?
By the way, I do not have such problems with other packages (e.g. bootstrap,
gplots, etc.) that I installed under RGui, and which I can use after
installation.
I nearly suspect that this problem was already reported, but I have just now
re-subscribed to this mailing list and could not find anything in the Newcastle
R archives. Could somebody be kind enough to resend a solution, if this problem
was already raised here in this forum (but not yet fixed in the Windows
binaries...).
thank you!
