Dear expeRts,
    When i using the following code, i get a error as follows:

 edit(file=vignette("grobs",package = "grid"))
Error in edit.vignette(file = vignette("grobs", package = "grid")) : 
  argument "name" is missing, with no default

I investigated edit function, but still can't  get codes from a vignette, May you help me?
