Sundar,

Thanks for the assistance.

Much appreciated.

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), ...)

HTH,

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

graph.sets <- list(axis.text = list(cex = 0.65),

? ? ? ? ? ? ?par.ylab.text = list(cex = 1.25),
? ? ? ? ? ? ?par.xlab.text = list(cex = 1.25))

? barchart(gator_IR$MEAN ~ gator_IR$Hydro |

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.
