For this to work you need an active internet connection, no firewall
restrictions, or any restrictions that would prevent R from copying files to
your hard disk. There may be other mac specific issues here I am not aware
of. See the R manual on installing packages.

Subject: [gov2001-l] Help with R
I'm having some problems with some of the packages. So in working through
Section1worksheet.r
when I write this code:
install.packages("car")
I get this error message:
Warning in install.packages("car") :
argument 'lib' is missing: using
'/Users/JeremyH/R/powerpc-apple-darwin8.10.1-library/2.6'
--- Please select a CRAN mirror for use in this session ---
Warning: unable to access index for repository
http://www.sourcekeg.co.uk/cran/bin/macosx/universal/contrib/2.6
Warning message:
package 'car' is not available
Can anyone suggest what I should do?
