Should that be True, False and File Not Found? ;)

I hate it when it comes to predicate optimisation, and bug reports from people who don't love it.

I boggled when I first was doing excel macros and discovered that there were the visibility options visible, hidden and very hidden.

Any kind of logic is all right with me, it's things completely lacking in logic that I'm not generally so keen on :)

Of course the only sensible answer is yes and no. There are many times when I've thought SQL should have a MAYBE operator to go with LIKE and SOUNDEX, but I keep wanting to SELECT UNTO things.

I meant to say- if you think SQL is bad, R uses an inconsistent ternary logic model. Witness:

> NA & TRUE
[1] NA
> tmp <- c(1,2,3,NA)
> tmp>=3
[1] FALSE FALSE TRUE NA
> tmp[tmp>=3]
[1] 3 NA

Yes, that's right, the array selection syntax treats NA as TRUE.
