OK, I take that back, at least until I've read that article. It
depends on how you use spreadsheets. Summing a column is not
programming, but yes, there is a second page, or sheet, to
spreadsheets.

What is R?

Yes. And as long as you don't do that fancy cursor iteration and
stuff, perhaps it is simply a computer implementation of
relational algebra, with some glue to make it stick together with
everything else, that is the computer (like the indexes, and
ordered sets - of course you don't need that in an abstract, math
model, that shouldn't be searched or otherwise optimized)?

Never heard of. What is that, set theory + programming, as in the
"set language"?
