[R] Incorrect permissions to edit database package

[michael watson (IAH-C)]

Hi

I am running R 2.0 on Suse Linux 8.2.  I get an error message when
loading a library:

"Incorrect permissions to edit the package database,
/usr/lib/R/library/liblisting.Rda: save.locLib(locLibList, curLib)"

However, when I look at that file, the user I am running R as has r and
w permissions on it....

So firstly - any ideas why I get this error message?  And secondly, does
it matter that I am getting it?  I don't get it if I run R as root
(obviously) but I don't really want to be doing that (obviously)

Cheers
Mick
