Thanks for replying Brian.
Indeed, I am working on windows (XP).
I tried doing:
dev.new(record = T)
And got:
Warning message:
‘mode(record)’ differs between new and previous
==> NOT changing ‘record’
But if I understood you, I could open a window with a plot, then open a new
one (with different dimensions), and then close the old plot device, while
still keeping all my record. Did I get this correctly ?
Yes: it worked for me when I tried it.
(if so, I would love a simple example of how that can be done using the
record = T)
It is windows() and not dev.new() that you need to call with
record=TRUE.
Thank you very much!

You haven't mentioned an OS nor a graphics device, So I will
guess Windows and windows(), since that is commonest device with
a history.

Hello dear R-help members,
Very soon I am to give a lecture on R. And in that
lecture I intend to move
between: par(mfrow = c(1,1)) to par(mfrow = c(1,2))
back and forth.
I anticipate this will damage the image proportions
and will force me to
resize the window.
So far I have found it is possible to close the
window and then reopen it
(bigger/smaller) by using:
dev.off()dev.new(width=5, height=4)plot(1:20)
The issue with this solution is that I loose all the
history I had with
these windows.
Thus, my question is either of two:
1) Can I resize a plot window AFTER it was created ?
Not programmatically. But you can have more than one device open and
switch between them by dev.next/dev.set ....
2) can you save and load a plot history, for between
closing and opening a
graphic device ?
Yes, from the menu. There is also the more general
recordPlot/replayPlot mechanism.
But note that the windows() plot history is shared between devices, so
if you work with multiple windows their histories will be interleaved.
It is a history _of the session_ and so you can page back into the
history of previously opened devices.
So I would do this by opening a device with record = TRUE, and when I
needed a different aspect ratio, open one with record = FALSE and
close it when I was done with it.
Thanks for any help,
Tal
