Multiple Devices

At any one time, any number of graphics devices may be present, but only one is active. To list all open devices use dev.list. To identify the active device use dev.cur, and to make a device current use dev.set. The functions dev.next and dev.prev makes the next or previous device active.

This allows two plots to be displayed separately.
