Did you? Not to put too fine a point on it, but this particular
question spurred a lengthy thread over the weekend about how polite
one should be (or not) to people who obviously haven't read the FAQ...
This is Question 7.21, to be precise.
Short answer: use assign(paste(...)) if you must, but you're usually
better off constructing a list, for instance like this:
> a <- 1:5 ; l <- lapply(1:5,function(i) a[i:5])
> l
