BTW,If someone is willing to help with two questions - we can extend the
small code I just wrote to other OS's. It might be useful for future people
who will present R graphical outputs to an audience.
But none of the other standard devices supports recording.
The questions are:
1) What is the equivalent of the command "windows" to other OS ?
X11() or quartz(), but see options('device'), and e.g. under JGR
(some) people prefer JavaGD ... and so on.
Usually dev.new() is fine: I think your error was to use 'T' when I
wrote 'TRUE'.
2) How can you get from R what OS is running it ?
I try
sessionInfo()$R.version$os
but it gives me:
"mingw32"
Which I am not sure how to connect between this and "windows XP"...
Why do you think there is a connection?

Thanks Brian,I wrote a tiny script employing your answer.
resize.win <- function(Width=6, Height=6)
{
# works for windows
dev.off(); # dev.new(width=6, height=6)
windows(record=TRUE, width=Width, height=Height)
}
resize.win(5,5)
plot(rnorm(100))
resize.win(10,10)
plot(rnorm(100))
Best,

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
