[R] lattice.xyplot: adding grid lines

[Deepayan Sarkar]

Sorry, that's what you get when you don't run your code before sending it. 
Should be panel.superpose instead of panel.xyplot, since you want a grouped 
display. e.g.,

xyplot(Sepal.Length + Sepal.Width ~ Petal.Length ,
       data = iris, allow.multiple = TRUE, scales = "same",type="l",
       panel = function(...) {
           panel.grid(h=2, v= 3, col="blue")
           panel.superpose(...)
       }
)
