Using Acrobat Reader to view PostScript!  It is a PDF viewer.

Acrobat Distiller has an auto-rotation option (on by default) when 
converting PostScript to PDF, which ghostscript later copied.  I 
suspect you need to track down where conversion to PDF is happening 
and disable auto-rotation.

      If you see problems with postscript output, do remember that the
      problem is much more likely to be in your viewer than in R.  Try
      another viewer if possible.

What happened when you followed that request?
