R help - Oct 2009 - multiple groups with different colors in boxplot

Can anybody help me on how to boxplot multiple groups with different color?
Say, I have 3 groups of data, each group with 2 boxes, and I'd like to have
the following layout in the boxplot:

red, red, green, green, blue, blue

thanks in advance.

Here is a solution using ggplot2

n <- 1000
dataset <- data.frame(A = rep(1:6, n), B = rep(gl(3, 2), n))
dataset$C <- with(dataset, rnorm(n) * as.numeric(B) + A)
library(ggplot2)
dataset$A <- factor(dataset$A)
#with default colours
ggplot(dataset, aes(x = A, y = C, colour = B)) + geom_boxplot()
#with custom colours
ggplot(dataset, aes(x = A, y = C, colour = B)) + geom_boxplot() +
scale_colour_manual(breaks = c("1", "2", "3"),
values = c("red",
"green", "blue"))

HTH,

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.
~ Sir Ronald Aylmer Fisher

The plural of anecdote is not data.
~ Roger Brinner

The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of
data.
