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

[Pengcheng Yang]

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,...)
          })
