[R] call function immediately before plot.new()

[Matthias Kohl]

Hi Jake,

are you looking for argument "panel.first" of "plot.default"?
?plot.default

panel.first: an expression to be evaluated after the plot axes are set
          up but before any plotting takes place.  This can be useful
          for drawing background grids or scatterplot smooths.

hth,
Matthias
