[R] How do I change the colour and format for the trelli plot ?

[ychu066]

I want to change the colour of the histogram in each panel by the levels of
the conoditonal factor.

I have 3 levels in the factor 

levels(data[,2])[1]     
levels(data[,2])[2]
levels(data[,2])[3]

what can i do , in order to chnage the colour ??
