I'm having problems installing packages.
I'm working on the R version 2.13.1 in a Mac OS X version 10.6.8.
I'm not able to search or install packages. For instance, I have the
following error message:
install.packages("lattice")
Warning: unable to access index for repository
http://cran.pt.r-project.org/bin/macosx/leopard/contrib/2.13
Looks like a weird URL. How did you come up with that one? When I go
to it with my browser it times out. Why not pick a working repository?
Warning message:
In getDependencies(pkgs, dependencies, available, lib) :
package 'lattice' is not available (for R version 2.13.1)
And I thought lattice was part of the default packages installation,
so would not have expected any need to install it.
Have you just tried library(lattice) from the R console?
