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

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.
Regards,

Parallel does not directly support that, and will insist on scaling
the data. However, you can control the scaling (using 'lower' and
'upper'), and override a couple of other arguments to get what you
want:

parallel(~iris[1:4] | Species, iris,
         xlim = extendrange(range(iris[1:4])),
         scales = list(x = list(at = NULL, labels = NULL)),
         lower = 0, upper = 1)

This is for horizontal.axis = TRUE, adjust accordingly for FALSE.

I have readjust the script as follows to retain the complete information 
of original graph, the background vertical bar.


parallel(~iris[1:4] | Species, iris,horizon=FALSE,
          ylim = extendrange(range(iris[1:4])),
          scales = list(y = list(at = NULL, labels = NULL),x=list(rot=45)),
          lower = 0, upper = 1,
          panel=function(x,y,z,...){
            panel.abline(v=1:4,col="gray90")
            panel.parallel(x,y,z,...)
          })
