dev.interactive          package:grDevices          R Documentation

Is the Current Graphics Device Interactive ?

Description:

     Test if the current graphics device is interactive.

Usage:

     dev.interactive(orNone = FALSE)

Arguments:

  orNone: logical; if 'TRUE', the function also returns 'TRUE' when
          '.Device == "null device"' and 'getOption("device")' is among
          the interactive devices.

Details:

     The 'X11' (Unix), 'windows' (Windows) and 'quartz' (MacOS X) are
     regarded as interactive, together with 'GTK' and 'gnome' (used
     with the GNOME GUI: 'GTK' is available in package 'gtkDevice' and
     'gnome' is expected to be in a package 'gnomeDevice') and 'JavaGD'
     (from the JGR project, see <URL:
     http://stats.math.uni-augsburg.de/JGR/>).

Value:

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