One possibility is:
f <- function(a, b, x) if (missing(x)) a+b else a-b-x

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),
Hi Ben,
Thanks for your answer. I looked at the status of VLA on the GCC
homepage and it appears to be "broken". [1] Do you think that the code
below still works? Or are you using a different compliler?

Tamas,
You could write convenience functions, but I have used the C99 mechanism
for variable length arrays with no problems calling from R. One thing
you have to keep in mind though is that (as far as I know) the
dimensions must be passed before the array reference. So for example,
r <- .C("fo
