I think you missed the question, Henrik, which was directed at updating
the local 3.1 library with all of the packages that were in the 3.0
library.
The usual advice for this is to copy your 3.0 library onto your 3.1
library (duplicate directory structure) so R knows what packages you want
to use and then use update packages. In general the copied directories
will not work directly, but R can update them. Note that some packages are
dropped due to better support in different packages or lack of maintainer
activity, so not all packages thus copied may end up usable.

Hi list
I've signed up for a Coursera course on exploratory data analysis, and the
recommendation is to update to R base 3.1.1. I'm currently on 3.0.2.
If I do upgrade, what is the best way for me to upgrade all my packages for
compatibility? Would this be accomplished through the command:
update.packages()
Also, any ideas what percentage of the packages have been updated to work
with 3.1.1. ? I'm just wanting to do a risk evaluation because I don't want
to lose access to packages such as ggplot2, sna, statnet, FactoMineR, and
several others through upgrading.
All package on CRAN should be up-to-date (that's almost the definition
of CRAN; if a package is not updated in time it's likely to be
archived due to lack of maintenance). When in doubt, have a look at
their individual CRAN pages, e.g.
http://cran.r-project.org/package=ggplot2. Look for the "r-release".
Note that "r-release" always refers to the latest stable official R
release, which currently is R 3.1.2. You should upgrade to that
version and not 3.1.1. It's pretty safe to always install the most
recent stable release version of R. If you're using an old version of
R, like you do, it's more likely that you run into problems in general
than if you use the most recent version. So, avoid sticking with old
version and make to upgrade whenever a new release come out.

Thanks for any steers
