[R] !0 + !0 == !0 - !0

Hi all,

The subject line is TRUE.

Today I accidentally typed rnorm(!0).

My old eyes took a minute to focus clearly enough to see what I really typed and
why I got '!0' random numbers instead of '10' random normal numbers.

If the subject line is disturbing, be assured that this is TRUE:

 !0^2 == !0 * !0  #  ;-)

Anyway, I hope the hands who have been around long enough to know FAQ 7.31 by
heart and know why precedence of operators matters have a laugh.

Best,

Chuck
