Why not just f <- g ?

Regards,

> f <- function(...) g(...)

> f <- function(a=1, b=2, c=3) g(a=a, b=b, c=c)

> This comes up in ggplot2 where I alias many functions to hide the fact
> that I'm using proto in the background, and I'd like the aliased
> functions to be a little more user friendly in terms of revealing what
> are valid arguments (and also to match up with the rdoc files which I
