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.
Try plotting after changing the size and re-querying "din":
> par("din")
[1] 7 7
<change window size>
> par("din")
[1] 7 7
> plot(1,1)
> par("din")
[1] 3.940054 7.268841
<change window size again, but no replotting>
> par("din")
[1] 7.144498 4.899888

Dear R-listers,
I am writing a function that will generate a simple plot for the
user . The size of the window (that contains the plot) may not be
what the user wants.
Supposing the user adjusts the window to a size of her/his choice, I
would like to be able to save the new window size and specify the
plot to be of this new window size when the user calls my function
again. My question is what is the kind of 'get' or save graphic
parameter command that I need to extract the size of the current
window? I have looked at 'par' and 'getOption' but they don't seem
to what I need.
From the help for par:
̔din̓ _*R.O.*_; the device dimensions, ̔(width,height)̓, in
inches.
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.)
Many thanks for any advice in advance.
Best wishes,
Edmond
