Dear Malcom, Another option is to merge both dataset to one big dataset and then plot the big dataset.
d1 <- data.frame(a = c(rep(1:3, each = 3)), b = c(1:9), d = "A") d2 <- data.frame(a = c(rep(1:3, each = 3)), b = c(9:1), d = "B") Dataset <- rbind(d1, d2) library(ggplot2) Dataset$a <- factor(Dataset$a) ggplot(Dataset, aes(x = a, y = b, colour = d)) + geom_boxplot() HTH, Thierry ------------------------------------------------------------------------ ---- ir.
