Raincloud plot

Source: R/marks.R
mark_raincloud.Rd

mark_raincloud() is a convenience that composes a raincloud: a one-sided density "cloud" (mark_halfeye()) with the raw observations as "rain" below it (mark_point() with sina spread). It is exactly plot |> mark_halfeye(...) |> mark_point(..., position = position_sina()), so any color/fill mapping in ... flows to both layers.

Usage

mark_raincloud(plot, x, y, ..., width = 0.4, alpha = 0.5)

Arguments

plot

A PlotSpec.

x, y

The categorical x and the sample y (tidy-eval).

...

Further shared encodings (e.g. color, fill) forwarded to both the slab and the points.

width

Sina spread of the rain, as a fraction of the band (default 0.4).

alpha

Point opacity for the rain (default 0.5).

Value

The modified PlotSpec.

Examples

set.seed(1)
d <- data.frame(g = rep(c("a", "b", "c"), each = 100),
                y = rnorm(300, rep(c(0, 1, 2), each = 100)))
vplot(d) |> mark_raincloud(x = g, y = y)
