@rpruim many thanks for your work on the mosaic/ggformula entropy!

Copying the reprex from the original {mosaic} issue for convenience.

suppressPackageStartupMessages(library(ggformula))
ggplot(mtcars, aes(x = 1, y = mpg)) +
    geom_violin(quantile.linetype = "solid")

gf_violin(mpg ~ 1, data = mtcars, quantile.linetype = "solid")
