Hi Rolf,
Thanks for the warning. I think because my initial efforts used the
assign function, that Jim provided his solution using it.
Any suggestions for how it could be done without assign() ?

Hi Jim,
Wow ! And it does exactly what I was looking for. Thank you very
much.
That assign function is pretty nice. I should become more familiar
with it.
Indeed you should, and assign() is indeed nice and useful and handy.
But it should be used with care and circumspection. It *alters the
global environment* which is fraught with peril. Generally speaking
most things that can be done with assign() (and its companion function
get()) are better and more safely done using lists and functions and
other "natural" R-ish constructs. Resist the temptation to turn R into
a macro language.
cheers,
Rolf Turner
