## List of Graphical Devices

### Description

The following graphics devices are currently available:

- `postscript` Writes PostScript graphics commands to a file
- `pdf` Write PDF graphics commands to a file
- `pictex` Writes LaTeX/PicTeX graphics commands to a file
- `xfig` Device for XFIG graphics file format
- `bitmap` bitmap pseudo-device via `GhostScript` (if available).

The following devices will be available if R was compiled to use them and started with the appropriate `--gui` argument:

- `X11` The graphics driver for the X11 Window system
- `png` PNG bitmap device
- `jpeg` JPEG bitmap device `GNOME` Graphics driver for the GNOME GUI.

None of these are available under `R CMD BATCH`.

### Usage

    X11(...)
    postscript(...)
    pdf(...)
    pictex(...)
    png(...)
    jpeg(...)
    GNOME(...)
    xfig(...)
    bitmap(...)

    dev.interactive()

### Details

If no device is open, using a high-level graphics function will cause a device to be opened. Which device is given by `options("device")` which is initially set as the most appropriate for each platform: a screen device for most interactive use and `postscript` otherwise. The exception is interactive use under Unix if no screen device is known to be available, when postscript() is used for most systems; pdf() for Mac OS X.

### Value

`dev.interactive()` returns a logical, `TRUE` iff an interactive (screen) device is in use.

### Examples

    ## Not run:
    ## open the default screen device on this platform if no device is
    ## open
    if(dev.cur() == 1) get(getOption("device"))()
    ## End(Not run)
