[R] Several Regression by combinations variables

[Bert Gunter]

In other words, "Abandon hope, all ye who enter..."

-- Bert

(Sorry, couldn't resist.  Berlioz's "March to the Gallows" from
Symphonie Fantastique also played in my head when I read Frank's
comment, but I couldn't put that in the email.)

"Men by nature long to get on to the ultimate truths, and will often
be impatient with elementary studies or fight shy of them. If it were
possible to reach the ultimate truths without the elementary studies
usually prefixed to them, these would not be preparatory studies but
superfluous diversions."

-- Maimonides (1135-1204)
