List of Graphical Devices

Description

The following graphics devices are currently available:

• pdf Write PDF graphics commands to a file

• postscript Writes PostScript graphics commands to a file

• xfig Device for XFIG graphics file format

• bitmap bitmap pseudo-device via Ghostscript (if available).

• pictex Writes TeX/PicTeX graphics commands to a file (of historical interest only)

The following devices will be functional if R was compiled to use them (they exist but will return with a warning on other systems):

• X11 The graphics device for the X11 windowing system

• cairo_pdf, cairo_ps PDF and PostScript devices based on cairo graphics.

• svg SVG device based on cairo graphics.

• png PNG bitmap device

• jpeg JPEG bitmap device

• bmp BMP bitmap device

• tiff TIFF bitmap device

• quartz The graphics device for the macOS native Quartz 2d graphics system. (This is only functional on macOS where it can be used from the R.app GUI and from the command line: but it will display on the local screen even for a remote session.)

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 pdf (or the setting of R_DEFAULT_DEVICE) otherwise. The exception is interactive use under Unix if no screen device is known to be available, when pdf() is used.

It is possible for an R package to provide further graphics devices and several packages on CRAN do so. These include other devices outputting SVG and PGF/TiKZ (TeX-based graphics, see http://pgf.sourceforge.net/).

## Not run: 
## open the default screen device on this platform if no device is
## open
