[R] Repost:lattice graphics -- legend color problems

Hello R-folks,

I don't get the color of the legend in a lattice-plot right. I select a palette from RColorBrewer and use (with a col = mypalette argument) it in the barchart plot. The resulting graph shows the new palette in the graph, but uses the standard palette in the legend rectangles.  Adding a col argument into auto.key uses the new palette with the legend text, but not in the rectangle fill. What am I missing?

TIA Joachim

---------code ---------

library("lattice")
library("RColorBrewer")
# palette auswählen

mypalette <- brewer.pal(7,"Accent")
pathBarchartFGE <- function(selector,data,dimension = 2,title = NULL,p = mypalette) {
# umwandeln für lattice Grafiken
dfvar <- as.data.frame.table(data)
names(dfvar) <- c("Zeitraum","FGG","Pfad","Fracht") dfsel <- subset(dfvar,dfvar$FGG %in% selector) barchart(Zeitraum ~ Fracht | FGG, layout = c(1,3), groups = Pfad, stack = TRUE , col = p, data = dfsel, xlab = "Einträge (t/a)",auto.key = list(title = "Pfade",columns = 2,space = "bottom"),main = title) }
