[R] Coplot

[Robert Abugov]

When I use the hills data in Maindonald's text (below) and apply

coplot(time ~ distance | climb, data=hills, overlap=0.0, number=3)

the graphs do not appear to line up with the conditional axis climb.
Is this a bug or am I missing something as an R newbie?

Thanks,

Bob Abugov
