Dear List-Members, I would like to produce a ordered boxplot in which the categories with the smallest median are plotted at the left end and the box with the largest median at the right. Thanks in advance for any advices Thomas H.

?reorder.factor shows the follwing example:
bymedian <- with(InsectSprays, reorder(spray, count, median))
boxplot(count ~ bymedian, data = InsectSprays,
xlab = "Type of spray", ylab = "Insect count",
main = "InsectSprays data", varwidth = TRUE,
col = "lightgray")

you could use the 'at' argument of boxplot(), e.g., y <- c(sapply(c(10, -5, -10, 5, 0), rnorm, n = 100, sd = 1)) gr <- gl(5, 100, labels = LETTERS[1:5]) boxplot(y ~ gr, at = rank(tapply(y, gr, median))) I hope it helps.
