        Just issue the par() command, and if no device is open, an
        x11 window will be opened automatically. Sean Davis's
        assertion that ``you must have an open graphics window before
        par has an effect'' simply isn't true. At least it's not
        true under R 1.8.1 on Solaris nor under R 1.9.0 on Linux.
