... and in general panel.whatever for whatever() lattice functions.
Typically graphical parameters are passed though the ... arguments. You need
to **carefully** read the docs.

Subject: [R] lattice package: Changing colors in graphs
Giving different colors to plots of different levels of a factor can
be pleasing. For a boxplot, for example, the following produces a nice
plot:
boxplot(len~supp*dose, data=ToothGrowth,
col=c("orange","gray"))
If I try to specify (using the lattice package)
histogram(~len|supp*factor(dose), data=ToothGrowth,
col=c("orange","gray"))
the effect is unexpected! (and certainly not desirable)
How does one do the same with histograms using the lattice package?
Also, how do I get more control over the colors of the "title bars"
for each pane in the lattice of graphs using the lattice package?
Ravi
