[R] 4th corner analysis ade4 - what do the colors mean

[Stephen Sefick]

I have used the fourthcorner function as suggest by dray and legendre 
(model 2 and 4 then combine).  I plot the combined value with 
plot(four.comb, type="G").  What do the colors mean?  I have both grey 
and black bars.
many thanks,

Stephen
