It is if you are running R on Linux (in which the X Windowing
System -- or X -- is the standard graphical system). As it
says in "?X11":

  "This can only be done on machines that run X."

Then each call to X11() opens a new graphics window, so you
can have as many as you like.

And, using the "display" parameter in X11(), if you have monitors
for more than one machine on your desk you can "throw" each window
to a monitor of your choice, giving you multiple graphics windows
on multiple screens, all from the same run of R.

But, as to whether/to what extent X or equivalent is available for
MS Windows, that is another question on which I have no expertise.
