How graphics windows work depends on the platform in both R and S-PLUS.
For R under Unix-alikes (which darwin is) there are no menus on a graphics
window. (It is an R graphics window, not a Lattice window, BTW.)
The Windows and Carbin ports of R do have such menus, as does the
gnome GUI front-end for Unix.  (You might want to explore the latter if it
is provided on your build.)

That works under Linux and Windows, so presumably something is up with
your build of R.

More usefully, which version of R, lattice and grid are you using?
You said it was `gray': because of the bug the current version of lattice
for R 1.4.1 uses a white background, so I suspect yours is not current.

You may want to wait a week until R 1.5.0 is released. That will ship with
lattice, and the grid/lattice packages included have been considerably
improved since 1.4.1.
