            plsdiori
          ( | rot ); | 
      Set plot orientation parameter which is multiplied by 90° to
      obtain the angle of rotation.  Note, arbitrary rotation parameters
      such as 0.2 (corresponding to 18°) are possible, but the usual
      values for the rotation parameter are 0., 1., 2., and 3. corresponding
      to 0° (landscape mode), 90° (portrait mode), 180°
      (seascape mode), and 270° (upside-down mode).  If plsdiori is
      not called the default value of
      
         is 0.
    rot
      
      N.B. aspect ratio is unaffected by calls to plsdiori.  So you will
      probably want to change the aspect ratio to a value suitable for the
      plot orientation using a call to plsdidev or the command-line
      options 
         or
      -a
      
        .  For more
      documentation of those options see the section called “Command Line Arguments”.  Such
      command-line options can be set internally using -freeaspect
      plsetopt or set
      directly using the command line and parsed using a call to
      plparseopts.
