Dear Prof Ripley,
Thank you very much for your advice. In fact, I have already tried
'par("din")'. It does not seems to pick up the changes made to the
window. For example, I issued the par command after the plot:
> par("din")
[1] 7.5 7.0
[changed window size]
> par("din")
[1] 7.5 7.0
The result is exactly the same after changes made to the window. Thanks
again.
Best wishes,
Edmond

seems to be exactly what you are asking for.
(I'd be cautious about saving this across sessions: users may well use
R on different computers with a common file system.)
