[R] How to *completely* stop a script after stop()?

[William Dunlap]

Put an open brace in the first line of your file
and a close brace in the last line.

I encourage people with scripts long enough that this
is a problem to divide up their work into functions
that a shorter script calls.  (This is akin to UCSD
Pascal on the Osbourne II that refused to deal with
a function that could not fit onto the tiny screen
-- it forced you do divide things up into small
understandable chunks of work.)
