Try:
edit(vignette("grobs",package = "grid"))
(edit is a method. It looks at the class of the first entry, name, to identify
which method to use. See ?edit. You want it to use edit.vignette, so you need
to drop 'file=' so you pass the vignette to edit as the first argument or
name=. Then edit will pass it to edit.vignette and it'll work. Or go direct:
edit.vignette(vignette("grobs",package = "grid")). See ?vignette. Maybe the use
of name as the first argument of a method is a little misleading? But you can
work out what is going if you work through the help documentation.)
