[R] adding an argument to ...

[cgenolin at u-paris10.fr]

Hi the list

Is it possible to add one argument to the arguments contain in ... ?

I would like to do :

f <- function(ttt,...)[
    if(... does not contain the args uuu)
        [add uuu=3 to ...]
        else[]
    g(ttt,...)
]

More precisely, my function g is a callNextMethod()

Thanks

Christophe
