Should the line/ribbon be drawn as a step function? One of:
FALSE (do not draw as a step
function, the default),
TRUE (draw a step function using the

"hv" (draw horizontal-then-vertical steps),
(draw as vertical-then-horizontal steps).
TRUE is an alias for
"mid" because for a step function with
"mid" is probably what you want (for the other two step approaches the ribbons at either the
vert first or vert last x value will not be visible).
Whether this geom is drawn horizontally (
"vertical"). The default,
NA, automatically detects the orientation based on how the
aesthetics are assigned, and should generally do an okay job at this. When horizontal (resp. vertical),
the geom uses the
x) aesthetic to identify different groups, then for each group uses
y) aesthetic and the
thickness aesthetic to draw a function as an slab, and draws
points and intervals horizontally (resp. vertically) using the
ymax) aesthetics. For compatibility with the base
ggplot naming scheme for
"x" can be used as an alias for
"y" as an alias for
"horizontal" (tidybayes had an
orientation parameter before ggplot did, and I think the tidybayes naming
scheme is more intuitive:
"y" are not orientations and their mapping to orientations is, in my
opinion, backwards; but the base ggplot naming scheme is allowed for compatibility).

TRUE, missing values are silently removed.

NA, the default, includes if any aesthetics are mapped.
FALSE never includes, and
TRUE always includes.
It can also be a named logical vector to finely select the aesthetics to
FALSE, overrides the default aesthetics,
rather than combining with them. This is most useful for helper functions
that define both data and aesthetics and shouldn't inherit behaviour from
the default plot specification, e.g.

geom_lineribbon is a combination version of a
geom_ribbon designed for use
with output from
point_interval(). This geom sets some default aesthetics equal to the
column generated by the
point_interval family of functions, making them
often more convenient than a vanilla
geom_lineribbon acts as if its default aesthetics are
aes(fill = forcats::fct_rev(ordered(.width))).
