David,

   My attempts at adding lattice.options to .Rprofile fail. In that file is

lattice.options(trellis.par.set(list(
                 box.umbrella=list(col="black"),
   		box.rectangle=list(col="black")
                      )
 		))

and invoking R within emacs displays this warning:

Warning message:
In trellis.par.set(list(box.umbrella = list(col = "black"), box.rectangle = list(col = "black"))) :
   Note: The default device has been opened to honour attempt to modify trellis settings
[Previously saved workspace restored]

   Removing the enclosing lattice.options() produces the same error. In
section 7.1.4 I'm not groking the correct syntax to change the color of both
box items within ~.Rprofile.
