Indeed; I typed the code into the email separately from typing it into
my R window.  (Bad move!)  I did try the code out (honest!) but then
retyped when I sent my email r.t. copying and pasting.  (Copying and
pasting on a Mac --- on which I am forced to work --- is fraught with
frustrations.)

P. S.  PolynomF seems to be slickly designed.  But then, what do you
expect?  Bill Venables wrote it!
