[R] A rebel boxplot question

[ONKELINX, Thierry]

I've altered the code slightly so one group has no data in one month.

  library(ggplot2)
  dataset <- data.frame(Month = factor(rep(1:12, 20)),  Value =
c(rnorm(120) + 1:12, rnorm(120) + 12:1), Group = gl(2, 120, labels =
LETTERS[1:2]))
  dataset <- dataset[dataset$Month != 2 | dataset$Group != "A", ]
  ggplot(dataset, aes(x = Month, y = Value, colour = Group)) +
geom_boxplot()

Cheers,

Thierry
