Create a cloud of randomly jittered points below a ridgeline plot which can be shifted horizontally

Description

This is a position adjustment specifically for 'geom_density_ridges()' and related geoms. It only jitters the points drawn by these geoms, if any. If no points are present, the plot remains unchanged. The effect is similar to position_points_jitterx(), only that by default the points lie all underneath the baseline of each individual ridgeline. It add 'hexpand' that can control shift horizontally.

Usage

position_raincloudx(
  width = 0,
  height = 0.4,
  ygap = 0.05,
  hexpand = NA,
  adjust_vlines = FALSE,
  seed = NULL
)

Arguments

width	Width for horizontal jittering. By default set to 0.
height	Total height of point cloud. By default 0.4.
ygap	Vertical gap between ridgeline baseline and point cloud.
hexpand	numeric, distance to be shifted horizontally for geoms that have a position, default is NA.
adjust_vlines	If TRUE, adjusts vertical lines (as are drawn for quantile lines, for example) to align with the point cloud.
seed	Random seed. See position_points_jitterx.

Details

The idea for this position adjustment comes from Micah Allen, who proposed this type of plot in a blog post on March 15, 2018.
