Why is jittered_points parameter missing from geom_density_ridges

[ghost]

Issue

Typing the following returns the function parametes for geom_density_ridges:

require(ggplot2)
require(ggridges)
require(ggpubr)
require(dplyr)

arcgs(geom_density_ridges)

result:

geom_density_ridges
function (mapping = NULL, data = NULL, stat = "density_ridges",
    position = "points_sina", panel_scaling = TRUE, na.rm = FALSE,
    show.legend = NA, inherit.aes = TRUE, ...)
{
    layer(data = data, mapping = mapping, stat = stat, geom = GeomDensityRidges,
        position = position, show.legend = show.legend, inherit.aes = inherit.aes,
        params = list(na.rm = na.rm, panel_scaling = panel_scaling,
            ...))
}

<environment: namespace:ggridges>

However, there is no sign of parameter jittered_points.

What happened to jittered_points?

I was following a tutorial on how to use ggridges and was interested in creating a rug simulation underneath each density plot with jittered points, such as in this example: https://cran.r-project.org/web/packages/ggridges/vignettes/introduction.html

Here is an example code:

p1 <- ggplot(data=df, aes(x=xVar, y=factorVar, group=factorVar, fill=stat(x)))
p1 <- p1 + geom_density_ridges(jittered_points=TRUE, scale=0.95, rel_min_height=0.01,
                point_shape='|', point_size=3, size=0.25,
                stat="identity", alpha=0.2, position=position_points_jitter(height=0))
p1 <- p1 + scale_color_brewer(palette="YlGnBu")
p1 %>% print()
