[R] how to label customized y axis when using lattice parallel parameter common.scale=TRUE

[Pengcheng Yang]

Dear all,

When I use parallel function in lattice package, I want to label the 
y-axis with customized numbers. Like this:

parallel(~iris[1:4] | Species, iris,horiz=FALSE,common.scale=TRUE,
     scales=list(y=list(at=c(0,2,3))))

But only "Min" label in the y-axis, nothing happened. Could anyone help me?

Thanks.
