[R] printing captions in multiple panes

[David White]

Dear List,

I would like to add captions to a set of graphics. The graphs are each
composed of two scatter plots in an upper and lower pane.

I'd like to add a caption below the lower pane. The troubel I'm hitting is
that in order to fit the caption using mtext, I must increase the margins
for both panes-- these shrinks my plots considerably and leaves a big
blank area.

The second trouble I'm having is to get the mtext to appear at the left
margin.

I see that ?mtext refers to the possibility of placing the text in the
outer margin. What is this?

the look I want is:
