setting trellis auto.key color values

I'm working with Lattice graphics and I would like very much to color code
the auto.key fill color with the same corresponding colors that I use in
the panels.  I've looked on the web for clues, and on the CRAN-R help sites
searching on "trellis auto.key color" and variations, unfortunately the
responses there are not very specific.

 Would someone please explain   I have the Book, if you can point me to the
pages that explain this I'd appreciate that too
par.ylab.text = list(cex = 1.25),
              par.xlab.text = list(cex = 1.25))
as.factor(gator_IR$IR_ID),layout=c(4,1),col = c(3:5),
                 groups=gator_IR$Rain, ylim=c(0,1), par.settings =
graph.sets,
                 main = "Alligator Nesting Performance", ylab= "Mean HSI",
                 auto.key = list("top", columns=3, col=c(3:5))


this script creates the graph nicely, with the qualification that the color
for the key titles are the correct, but the filling colors are default
pastels.  Where do I change them ?


Windows XP  with R 2.8.1

Thank you.

Set the colors in graph.sets and not auto.key.

graph.sets <- list(axis.text = list(cex = 0.65),
              par.ylab.text = list(cex = 1.25),
              par.xlab.text = list(cex = 1.25),
              superpose.polygon = list(col = 3:5))

Then remove the "col = 3:5" from auto.key and barchart.

Also, you can simplify your code by removing "gator_IR$" and including
"data = gator_IR". I.e.

 barchart(MEAN ~ Hydro | as.factor(IR_ID),
                 data = gator_IR, layout = c(4, 1),
                 groups = Rain, ylim = c(0, 1), ...)

Set the colors in graph.sets and not auto.key.

graph.sets <- list(axis.text = list(cex = 0.65),
              par.ylab.text = list(cex = 1.25),
              par.xlab.text = list(cex = 1.25),
              superpose.polygon = list(col = 3:5))

Then remove the "col = 3:5" from auto.key and barchart.

Also, you can simplify your code by removing "gator_IR$" and including
"data = gator_IR". I.e.

 barchart(MEAN ~ Hydro | as.factor(IR_ID),
                 data = gator_IR, layout = c(4, 1),
                 groups = Rain, ylim = c(0, 1), ...)
