[R] tree plot

[Prof Brian Ripley]

?par, look at xpd.

I haven't looked at your figures, but if you are plotting in less that the 
full device region you probably ought to both decrease the font size and
remove clipping to the plot region.  You probably want par(xpd=TRUE), and 
you may want to adjust the figure margins too.
