[R] Lattice: bwplot - changing box colors in legend and plot when using panel.groups = function... and panel = panel.superpose

[Duncan Mackay]

I had a similar problem and found when looking 
inside one of the lattice functions that the 
legend colours are controlled by the superpose 
series eg superpose.line, superpose.polygon etc
in trellis.par.set/get or par.settings
