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
Warning message:
In getDependencies(pkgs, dependencies, available, lib) :
package 'lattice' is not available (for R version 2.13.1)
Thank you in advance
Miguel
