R help - Mar 2004 - Moving to 1.8.1: can you transfer your package list?

I prefer to use R on a linux box and ultimately need things to end up 
there to serve things up using David Firth's excellent CGIwithR and 
apache, but one step at a time and I've installed 1.8.1 under win2k.  
Another question that I'm sure is simple: is there a simple way to 
find the list of installed libraries I had in my 1.7.1 installation 
and use that to drive install.packages?

I've done it with a rather ugly bit of copy and paste using library() 
in the 1.7.1 installation and then using install.packages("xxx") on 
each of the package names from the first column of the output from 
library().  How should I have done it more elegantly gurus?

TIA,

Chris

installed.packages(priority="NA")[, 1]

Can I suggest that with 1.9.0 imminent, you use that rather than 1.8.1.
The Windows build is at 
http://cran.r-project.org/bin/windows/base/rdevel.html

At the very least, use a version of R-patched (similar URL).

  ip <- installed.packages(lib.loc = "pathToYourOldLibraryDir")
  ip <- ip[ip[,1]!="base" ,1]
  install.packages(ip)
