[R] contributed packages not found

[Hank Stevens]

   Windows 2000, R 1.6.1
   When I try use the menu to download and install new packages, the
   result looks like this:
   {a <- CRAN.packages()
   + install.packages(select.list(a[,1],,TRUE), .libPaths()[1],
   available=a)}
   trying URL `[1]http://cran.r-project.org/bin/windows/contrib/PACKAGES'
   Error in download.file(url = paste(contriburl, "PACKAGES", sep = "/"),
   :
   cannot open: HTTP status was `404'
   Is this no longer the path to the packages? Can I fix this without
   updating R?
   Many thanks,
   Hank Stevens
