I'll leave that up to you... :-)
You could add the URL of the thread to the wiki entry if you wish as
well.

Is it possible to export a list of installed packages from WinXP,

No doubt
there is custom code that could be written, but I wonder if R
2.9.1 has
anything built it to do that? Is it as simple as moving something
like
Rprofile.site from one machine to the other?
I had a look at R-admin.pdf, and although it talks a lot about
configuring on various systems, it did not address this directly.
Also
looked at RSeek.
Thanks.
If you are just going to replicate a standard installation with
Base and Recommended packages, then just install R on Ubuntu (I
presume that you will use 'apt-get'"?) and you will have the same.
Review the following for more Ubuntu specific information:
http://cran.r-project.org/bin/linux/ubuntu/
If there are extra packages that you have installed on Windows,
then you can use the following to get the list:
IP <- as.data.frame(installed.packages())
MyPkgs <- subset(IP, !Priority %in% c("base", "recommended"),
select = c(Package, Bundle))
MyPkgs will now contain a list (first column) of the packages that
you have installed that are not part of the basic R install. In
addition, pay attention to the 'Bundle' column in case you have
installed any package bundles. Those would need to be installed
using the Bundle name and not the individual package name.
Before you go too far with this however, I would check to see just
how many packages are listed in MyPkgs. If the list is short (for
some value of short), you may be better just manually installing
the packages on your Ubuntu system rather than going through this
process.
The question then becomes, are you going to install these on Ubuntu
using 'apt-get' from the Ubuntu CRAN repos, or are you going to
install the packages from CRAN using install.packages(). I suppose
intertwined with that will be are there any packages that you have
installed that are not yet in the Ubuntu repos.
In either case, you can save 'MyPkgs' to an R readable object file
on Windows by using:
save(MyPkgs, "MyPkgs.Rdata")
Copy that file over to your Ubuntu installation and use:
load("MyPkgs.Rdata")
and you will have the MyPkgs object available there.
You can then use the list as you require.
If you are going to use install.packages() and presuming that you
do not have any bundles installed on your Windows system, you could
do the following after using 'sudo R' to go into R:
load("MyPkgs.Rdata")
install.packages(MyPkgs$Package, dependencies = TRUE)
If you are going to use 'apt-get', I would read the following as I
noted above:
http://cran.r-project.org/bin/linux/ubuntu/
You could feasibly create an 'apt-get' command line call using
paste() and the system() functions along the lines of:
CMD <- sapply(MyPkgs$Package, function(x) paste("r-cran-", x, sep
= ""))
CMD <- paste(CMD, collapse = " ")
CMD <- paste("apt-get", CMD)
and then use:
system(CMD)
after using 'sudo R' to get into R.
However, I would recommend that you consider posting a query to the
r-sig-debian list just to verify all of the above. More info at:
