It's very likely that there is already an R package for your linux
system, and, if so, you'd probably be well-served to use that one.
You've given us the version of the kernel you're using (not a recent

I've done a simple-minded transliteration of your code into code using nested

clarity, which is really one of the main advantages of the `apply` family).

I think Bert's advice is sound. Let me add a few, miscellaneous comments:
(1) Some people find "by" easier than "tapply".
(2) The "apply" function can, as I'm sure you (Bert) know, iterate
over a matrix.
(3) Hadley probably has better ways to do all of this (it's hard to keep up).

I can't tell what kind of structure you want to output, but one simple
