global option settings for grid and lattice?

Hello, I'd like to be able to set options for grid and lattice globally, once for all subsequent plots, just like what ps.options() does. I walked through the functions of Grid and didn't find it. The following are related things that are available: get.gpar() trellis.par.set() any ideas? thanks.
ps.options() sets the defaults for a PostScript output device. It has no effect, for example, on screen output. The top-level grid viewport takes most of its default settings from the device, so it should pick up ps.options() settings (WHEN you are drawing to a PostScript device). All grid drawing uses default settings from the current viewport unless explicitly overridden, so ps.options() settings should carry through to your drawing (IF you are only using grid). Lattice decides for itself what the default graphics settings should be (again, based on the type of device you are drawing to, but using lattice defaults, NOT ps.options() defaults). You might want to look at ?trellis.device and read about themes to gain control over default lattice settings. Paul
