hello

 If I have a a program



trend <- read.table("txx.csv", header=T, sep=",")
library(lattice)
trellis.par.set(theme = canonical.theme("postscript", col=FALSE))
trellis.par.set(list(fontsize=list(text=8),
                 par.xlab.text=list(cex=1.5),
                     add.text=list(cex=3.5),
                     superpose.symbol=list(cex=1.0)))
key <- simpleKey(levels(trend$Season), space = "right")
key$text$cex <- 1.5
print(
     dotplot(Ville ~ Slope , data = trend, groups = Season,
             key = key,
             xlab = NULL,
             aspect=0.8, layout = c(1,1), ylab=NULL)
)

and my dat det is

 Ville Season Slope significance  Alh DJF -0.3 0.02  Ben DJF 0.13 0.7  Cas
MAM 0.1 0.1  Ess JJA 0.4 0.03  Fes SON 0.9 0.02
how can i change the color of symbole of slope value if the significance is
below 0.05

thank you
