Lists of Open/Active Graphics Devices (original) (raw)

Description

A pairlist of the names of open graphics devices is stored in.Devices. The name of the active device (see[dev.cur](../../grDevices/html/dev.html)) is stored in .Device. Both are symbols and so appear in the base namespace.

Usage

.Device
.Devices

Details

.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".
