[R] plotting on the figure margin

[Paulo Barata]

Dear R-list members,

I am trying to put a legend just outside the plotting area
of a graph.

1. Is there some way to plot symbols on the figure margin,
in the same way as function "mtext" can write on the
margin?

2. Is there some way to use the "legend" function (or some
equivalent function) to plot a legend on the figure margin?

3. Any other way to plot either symbols or a legend
on the margin?

I use R 2.7.2, running on Windows XP.

Thank you very much.

Paulo Barata
