[R] Problem with Example with Lattice

Dear All,
I am making my baby steps with the lattice graphic system.
I am going through the great book by Sarkar which provides plenty of
However, I notice that some of them appear to give a different result
on my system.
For instance, consider the following


dotplot(VADeaths, type = "o",
auto.key = list(lines = TRUE, space = "right"),
main = "Death Rates in Virginia - 1940",
xlab = "Rate (per 1000)")

This should produce a plot where I have different point shapes
connected by different line shapes, but I only one point shape
connected by solid segments.
Am I misunderstanding something basic?
Many thanks
