[R] graphics reset

[Murad Nayal]

Hello,

Is there a specific command to clear the graphics window. On occasion I
need to construct plots using commands that don't clear the graphics
window (like text, lines and points etc.) -only- and hence need to clear
the graphics completely before hand. 

also, is there a way to restore the graphics parameters to default
values, say in these cases where you forgot to save the original values
and want to restore the graphics to some sane state after a long R
session.

many thanks
