List of Graphical Devices

Description

The following graphics devices are currently available:

• windows The graphics device for Windows (on screen, to printer and to Windows metafile).

• 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):

• 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

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/).
