[R] overlap dot plots with box plots

[Peter Ehlers]

Looks like you're just missing the 'add=TRUE' argument; see below.

  Maybe something like this:

boxplot(count ~ spray, data = InsectSprays, outpch = NA)
stripchart(count ~ spray, data = InsectSprays,
            vertical = TRUE, method = "jitter",
            pch = 21, col = "maroon", bg = "bisque",
            add = TRUE)

(Setting 'outpch = NA' avoids plotting outliers.)
