Hi I am running R 2.0 on Suse Linux 8.2. I get an error message when loading a library (affy): "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 ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html

I'm assuming 'yes' due to your stating that you're running R as root but do you also have write access on the directory as well? > So firstly - any ideas why I get this error message?

It is worth trying this from within R: file.access("/usr/lib/R/library", mode = 2) and if the result is non-zero then R believes that you in fact don't have write access. This does seem odd though - is it only when you're loading affy, or does it happen when loading other packages? -J
