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 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 Window system

• bmp Windows bitmap device

• jpeg JPEG bitmap device

• png PNG bitmap device

• tiff TIFF bitmap device

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

• quartz The graphics device for the Mac OS X native Quartz 2d graphics system. (This is only functional on Mac OS X, but unlike R < 2.7.0 can be used from the command line and not just from the GUI console.)

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.
