Randomly distribute points in a ridgeline plot between baseline and ridgeline

Source: R/position.R

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 a sina plot: Points are randomly distributed to fill the entire shaded area representing the data density.

position_points_sina(rel_min = 0.02, rel_max = 0.98, seed = NULL)

Arguments

rel_min

The relative minimum value at which a point can be placed.

rel_max

The relative maximum value at which a point can be placed.

seed

See position_points_jitter.
