Two Dimensional Box and Whisker Plots

Basic example using the mtcars dataset.

library(ggBoxes)
data(mtcars)
p <- ggplot(mtcars, aes(x = wt, y = mpg, group = factor(cyl), 
                        color = factor(cyl), fill = factor(cyl))) +
    geom_boxplot2d() +
    theme(legend.position = 'bottom')
p

We can add marginal density plots using the ggExtra package. We have to add the raw data points for the marginal plots to display. By setting alpha = 0 the points are present for the density plots but are hidden from the plot.

ggExtra::ggMarginal(p + geom_point(alpha = 0), 
                    type = 'density', 
                    groupColour = TRUE, 
                    groupFill = TRUE)

Example with Palmer's Penguins

library(palmerpenguins)
data(penguins, package = 'palmerpenguins')

ggplot(penguins, aes(x = flipper_length_mm, y = bill_length_mm, color = species, fill = species)) +
    geom_boxplot2d()
