_D_e_s_c_r_i_p_t_i_o_n:

     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:

        *  'X11' The graphics driver for the X11 Window system

        *  'png' PNG bitmap device

        *  'jpeg' JPEG bitmap device

_D_e_t_a_i_l_s:

     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.

_S_e_e _A_l_s_o:

     The individual help files for further information on any of the
     devices listed here;

     'dev.interactive', 'dev.cur', 'dev.print', 'graphics.off',
     'image', 'dev2bitmap'.

     'capabilities' to see if 'X11', 'jpeg' and 'png' are available.

_E_x_a_m_p_l_e_s:

     ## 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)
