I'd recommend upgrading.  I think it would be difficult to do this with 
a hook function:  you'd basically need to close the pdf file that Sweave 
opened, and reopen it with new args --- but I don't think it's easy for 
you to determine the filename that Sweave would have used.  You probably 
need to look at sys.frame(-2)$chunkprefix or something equally ugly.
