which
| An integer specifying a device number |
Only one device is the active device. This is the device in which all graphics operations occur.
Devices are associated with a name (e.g., "X11" or "postscript") and a number; the "null device" is always device 1.
dev.off
shuts down the specified (by default the current) device.
graphics.off()
shuts down all open graphics devices.
dev.set
makes the specified device the active device.
A list of device names is stored in .Devices
.
The name of the active device is stored in .Device
.
dev.cur
returns the number and name of the active device.
dev.list
returns the numbers and names of all devices.
dev.next
returns the number and name of the next device in the
list of devices.
dev.prev
returns the number and name of the previous device in
the list of devices.
dev.off
returns the name and number of the new active device
