Thanks, Henrique! I'm not sure this will help since the paths are already unique.

This line in this particular installation of R 2.6.1 on my Ubuntu 7.10 workstation reads: R_LIBS=${R_LIBS-'/usr/local/lib/R/site-library:/usr/lib/R/site-library:/usr/lib/R/library'} One question (for me, at least), is why did I start to get this warning message, to begin with? I wasn't getting it with an earlier version of R. The warning I'm getting started to appear after I updated from 2.5.1 to 2.6.1. I did this using the procedure described on: http://cran.cnr.berkeley.edu/bin/linux/ubuntu/ I used Ubuntu's Synaptic Package Manager to install R initially on this particular machine, from what I can recall. After updating to 2.6.1, the packages I had previously installed with 2.5.1 were in the directory /usr/local/lib/R/site-library. When I now install additional packages in 2.6.1, they are installed to this directory, and not to /usr/lib/R/site-library, the directory library() gives warnings about. My hypothesis is that the default library configurations for the two versions were different for some reason. Thanks, Henrique and Phil, for your help!
