A perfectly fine question for the list. I don't know the answer
off-hand . . .

With luck, some of the recent discussion on the list has helped with
lattice.
But, in general, Gary's point applies much more broadly. It is *not*
the case that we want you to spend an inordinate amount of time
"figuring out lattice". We want you to learn how to produce
publication-quality articles by doing high quality empirical
research. One, and only one, aspect of this is graphics. Good graphics
will help you make your points more clearly and increase the chances
that your articles get published.
So, you should not think: "I am stuck spending a bunch of time
on lattice so that Dave won't take off points on my final." You should
think: "I am wise to invest some time now in getting good at producing
nice looking and informative graphics so that articles I write down
the road are more likely to be persuasive and published".
Almost no one will ever care about the grade that you get in GOV
1000. Future academic hiring committees will care a lot about the
quality of your research. One small, but still meaningful, way that
they will judge that quality is by the quality of your graphics.

Has anybody figured out how to put in an abline (i.e. flat line or 45 degree
line) in lattice graphs? using abline(0,1) doesn't seem to do anything.
Thanks,
Phillip.

Subject: Re: GK Question
this is a fine question and well put. the answer, however, is
theoretical. I.e., we chose one definition of incumbency advantage. You
certainly could choose another. Whether one chooses one vs the other is
not a matter of inference but one of theory or preference or normative
choice.
