R help - Oct 2008 - lattice: overlap histogram

Dear R users,

Is it possible to have an overlap histogram plot? For example:

stuff <- data.frame(Mode = c("Land", "Air"), AgeGroup =
c("Young", "Adult",
"Old"), Value = sample(1:300))
histogram( ~Value | AgeGroup * Mode, data = stuff, auto.key = TRUE)

Instead of having 2 * 3 panel, I want to have just 3 panel, overlapping the
"Mode" into the same panel.

I tried the following:
histogram( ~Value | AgeGroup, data = stuff, groups = Mode, auto.key = TRUE)

but I think it gave me incorrect result.

Any help is appreciated.

Thank you,

Ferry

See

but I would recommend use of densityplot() instead:

densityplot( ~Value | AgeGroup, data = stuff, groups = Mode, auto.key = TRUE)
