Yes, this works.
Thanks Gabor!

That's because you are passing the argument twice. Try this:
> foo1 <- function(x, ...)
+ {
+ L <- list(...)
+ if (is.null(L$decreasing)) L$decreasing <- TRUE
+ do.call(order, c(list(x), L))

Actually it is not OK. Bellow is simplified example that shows, what I
would like to do:

Thanks!
Use of list(...) really helps me here.

Hello!
Say I have a function foo1, which has argument ... to pass various
arguments to foo2 i.e.
foo1 <- function(x, ...)
{
foo2(x, ...)
}
Say that foo2 accepts argument arg1 and I would like to do the following:
- if foo1 is called as foo1(x) then I would like to assign some value to
arg1 ins
