| \title{ |
| Lists of Open/Active Graphics Devices |
| } |
| \description{ |
| A pairlist of the names of open graphics devices is stored in |
| \code{.Devices}. The name of the active device (see |
| \code{\link{dev.cur}}) is stored in \code{.Device}. Both are symbols |
| and so appear in the base namespace. |
| } |
| \value{ |
| \code{.Device} is a length-one character vector. |
| |
| \code{.Devices} is a \link{pairlist} of length-one character vectors. |
| The first entry is always \code{"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 |
| \code{""} 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 |
| \code{"filepath"}. |
