There exists a reference work, in one sense, the archives of mathgroup.
If someone or a group would remove headers, clean it up a bit, index and
(press a cd? post to MathSource? searchable URL?) distribute it would
benefit everyone who uses Mathematica.
Until I had to work on a problem, I didn't pay much attention to the
functions of columns discussion, but found DataManipulation in the
Statistics package with most of the functionality needed.
Timing as a criterion for efficiency can't be matched. When a function
I had written didn't work in a reasonable time, examining the timing
exposed the flaw. Timing as a criterion for elegance is of less
importance to me; readablity, or understand-ability is what I need to
apply the techniques discussed to my work. In the five years I've used
the program, the speed of the machine I work on has gone from 261 seconds
to 10 seconds for the same calculation, with 5 seconds or less for the
machine coming this fall.
