.Device {base} | R Documentation |
A pairlist of the names of open graphics devices is stored in
.Devices
. The name of the active device (see
dev.cur
) is stored in .Device
. Both are symbols
and so appear in the base namespace.
.Device
.Devices
.Device
is a length-one character vector.
.Devices
is a pairlist of length-one character vectors.
The first entry is always "null device"
, and there are as many
entries as the maximal number of graphics devices which have been
simultaneously active. If a device has been removed, its entry will be
""
until the device number is reused.
Devices may add attributes to the character vector: for example
devices which write to a file may record its path in attribute
"filepath"
.
