[R] Plot legend in margin

[Greg Snow]

Another couple of things to think about:

You could use the layout function to set up your multiple plots and
include an extra plotting area at the bottom to place the legend in.

If you stick with the solution below then the cnvrt.coords function from
the TeachingDemos package may be useful (will help you find the
coordinates relative to the last plot).

Hope this helps,
