Hi Eric,

I have the same issue in Windows. When I upgrade, I just copy all the packages I need from the 2.12 to the 2.13 library folder and run update.packages afterwards. However, be careful not to replace any of the existing packages with older versions, as this might break the installation.

Running linux 10.04 ubuntu.

Looks like Ubuntu automatically updated to version 2.13. I was running
version 2.12 until today. But now I'm getting error messages when I use the
require or library command and one of the packages I've downloaded in the
past.  For example:

require(quantmod)
Loading required package: quantmod
Warning message:
In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return
= TRUE,  :
  there is no package called 'quantmod

I noticed under my Home folder in the R folder that I have a
i486-pc-gnu-library subfolder. Inside that sub folder are 3 subfolders
labeled 2.10, 2.12, 2.13. If I look in 2.12, I see a lot of subfolders with
the names of the packages I use (quantmod for instance). If I look in the
2.13 subfolder, there's nothing there at all; it's empty.

So what is the right course of action ?
