I don't think we can do that.  Look at her e-mail address.

Subject: [mg35543] [mg35525] Problems with simulating society ch4 section 4.3

Hi
I am hoping that someone can help me as I am fairly desperate for an
answer.
I am attempting to do two things: one to run a simulation from the
gaylord
and d'andria book "simulating society", the one on page89, section 4.3.
For
some unknown reason the simulation runs, however the graphical plot just
hangs for ever and ever. My computer does have the necessary power so I
don't know what the problem is. The second thing I am trying to do is
run my
own (partly) simulation of the repeated prisoner's dilemma, with two
types,
Tit-for-tat players and defectors, and have the two types interact, then
change their type depending on the average payoff in their immediate
Moore
neighbourhood, and then walk. For some reason I get the following error
which I have no idea how to get rid of ( this is why I am attempting to
run
the section 4.3 simulation as it does something similar).

I've attached the code of section 4.3 on the off chance someone knows
what
the problem is.
