I have now managed to sort out my problem, however I still cannot get the
graphical plot to run for either of these two simulations. If anyone has any
ideas as to why MultipleListPLots sometimes just hang without giving any
indication, could you please let me know.
thanks
Katherine Geel
This is the attempted plot:
avgResourceLevel[lat_, strat_] :=
    (Apply[Plus, #]/Length[#]) &[
      Cases[lat, {_, _, strat, _, x_} :> x, 2]];
<< Graphics`Graphics`
<< Graphics`MultipleListPlot`
Needs["Graphics`MultipleListPlot`"]
MultipleListPlot[
  Map[avgResourceLevel[#, 1] &, results],
  Map[avgResourceLevel[#, 0] &, results],
  SymbolShape -> None,
  PlotJoined -> True,
  PlotLegend -> {"Good Guy", "Bad Guy"},
  AxesLabel -> {"Time", "Resource Level"},
  LegendShadow -> {-0.05, -0.05}]
