[R] {Lattice} help.

[Greg Snow]

Here are a couple of others to try (using the lattice package):

dotplot(Factor1 ~ Value | Factor2, data=foo, groups=Factor3, auto.key=T)
dotplot(Factor1 ~ jitter(Value) | Factor2, data=foo, groups=Factor3, auto.key=T)
dotplot(Factor3 ~ Value | Factor2*Factor1, data=foo )
dotplot(Factor1:Factor3 ~ Value | Factor2, data=foo )

also see the dotchart2 function in the Hmisc package for another version of the dotplot.
