R help - Sep 2009 - Party plots

I'm pretty new to R, and not much of a progammer (yet).  I'm having
trouble
navigating the graphical output for the party algorithm.  Essentially, my
tree is too large for the default page size so the nodes overlap and obscure
one another.  Anybody know how to change the plot parameters to either:
     1) enlarge the page size so the default font fits comfortably
(preferred);
     2) shrink the graphics to fit the default page size (I worry that this
might make exports illegibly small); or
     3) show the tree in sections (not optimal, but servicable).

Any assistance offered is truly welcome.
Thanks

You can easily plot into a large PDF, e.g., something like this

   pdf(file = "foo.pdf", height = 15, width = 20)
   plot(foo)
   dev.off()

and then view the PDF in an external viewer, zooming into parts of a tree 
etc. Depending on the size of the tree in "foo", you might have to
adjust
height/width accordingly.

This is both a bit cumbersome in the current implementation. If you want 
to play around, you can use the re-implementation in package
"partykit" on
R-Forge which has more flexible plotting facilities. However, there is 
still not much documentation, yet. Hence, I would recommend to try the 
solution above to see whether it suits your needs...
