[ONKELINX, Thierry]

Try somelike this

library(ggplot2)
dow <- data.frame(dayofweek = factor(1:7), p = runif(7), w = c(0, 1, 1,
1, 1, 1, 0))
sc <- scale_fill_continuous()
sc$legend <- FALSE
qplot(dayofweek, p, data=dow, geom="bar", xlab="Day", ylab="Arrival
Rate", main="Spam by Weekday", fill=w) + sc

HTH,

Thierry

Do not put your faith in what statistics say until you have carefully
considered what they do not say.  ~William W. Watt
A statistical analysis, properly conducted, is a delicate dissection of
uncertainties, a surgery of suppositions. ~M.J.Moroney
