position_raincloud | R Documentation |
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_jitter()
, only that by default the
points lie all underneath the baseline of each individual ridgeline.
position_raincloud(
width = 0,
height = 0.4,
ygap = 0.05,
adjust_vlines = FALSE,
seed = NULL
)
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. |
adjust_vlines |
If |
seed |
Random seed. See |
The idea for this position adjustment comes from Micah Allen's work on raincloud plots (Allen et al. 2021).
