This meta-geom supports drawing combinations of functions (as slabs, aka ridge plots or joy plots), points, and
intervals. It acts as a meta-geom for many other tidybayes geoms that are wrappers around this geom, including
eye plots, half-eye plots, CCDF barplots, and point+multiple interval plots, and supports both horizontal and
vertical orientations, dodging (via the
position argument), and relative justification of slabs with their

geom_slabinterval is a flexible meta-geom that you can use directly or through a variety of "shortcut"
geoms that represent useful combinations of the various parameters of this geom. In many cases you will want to
use the shortcut geoms instead as they create more useful mnemonic primitives, such as eye plots,
half-eye plots, point+interval plots, or CCDF barplots.
The slab portion of the geom is much like a ridge or "joy" plot: it represents the value of a function
scaled to fit between values on the x or y access (depending on the value of
orientation). Values of
the functions are specified using the
thickness aesthetic and are scaled to fit into
times the distance between points on the relevant axis. E.g., if
scale is 0.9, and
y is a discrete variable, then the
thickness aesthetic specifies the
value of some function of
x that is drawn for every
y value and scaled to fit into 0.9 times
the distance between points on the y axis.
For the interval portion of the geom,
y aesthetics specify the location of the
xmax (depending on the value of
specifying the endpoints of the interval. A scaling factor for interval line width and point size is applied
These scaling factors are designed to give multiple uncertainty intervals reasonable

As a combination geom, this geom expects a
datatype aesthetic specifying which part of the geom a given
row in the input data corresponds to:
"interval". However, specifying this aesthetic
manually is typically only necessary if you use this geom directly; the numerous wrapper geoms will
usually set this aesthetic for you as needed, and their use is recommended unless you have a very custom
Wrapper geoms and stats include:
stat_sample_slabinterval() and associated stats
stat_dist_slabinterval() and associated stats
geom_* versions are meant for use with already-summarized data (such as intervals) and the
stat_* versions are summarize the data themselves (usually draws from a distribution) to produce the geom.
These geoms support the following aesthetics:
