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

[ychu066]

Fore example my code is 
histogram(~data[,8]|data[,2], ylab = "Frequency", xlab = "Score", xlim =
c(1,5), ylim = c(0,100),layout = c(3,1),col=data[,2] )

and i want the colour to be depended on the level of the factor in data[,2]. 
how do i do that ?
