Was going to suggest following up on the SIG-geo mailing list since the shape-shifters don't all hang out in these parts, but I see that you crossposted. (That's not considered good form on R mailing lists.)

This FAQ:

http://cran.r-project.org/bin/macosx/RMacOSX-FAQ.html

(I see 10 numbered major headings, although admittedly the 9th is the acknowledgements section. I'm wondering if it were the 7th section that was meant, since it has information about setting the locale.)
