I would like to take this:

.img(plot(1:10), filename="a")

and produce


ie. whenever .img is used, I want to take the first argument and throw away everything else.

(I am trying to produce a Sweave like environment in which I can apply certain functions, but not have them displayed in the output)

I think I should be able to do it using substitute, but I don't know how to operate on language objects. Any hints would be appreciated.
