One possibility is:
f <- function(a, b, x) if (missing(x)) a+b else a-b-x
although that does have the disadvantage that one cannot explicitly tell
it not to use x but rather its denoted by its absence.

Hi,
I am writing a collection of functions which I plan to share as a
package later (when they are tested thoroughly), so I would like to do
things "right" from the beginning...
I encountered a minor question of style. Consider a function
f <- function(a,b,x=NULL) {
## ...
}
if !is.null(x),
