The text is parallel to the axis -- so far, so good.  However, the text is rotated counterclockwise from horizontal, whereas I would like it rotated clockwise.

Hi Dennis,
This sounds like a job for twoord.plot (plotrix). I think I can leave 
the warnings, disclaimers and miscellaneous dissuasion to others.
