Dear all
Is it possible to programmatically detect which commands have
generated a graphic to the x11() graphics device? When in front of the
computer, it is easy to see that after a command---say, plot(1:10)---a
graphics window opens/activates and displays a graphic. But is there a
way to detect this from the command line?

Thank you
