geom_half_point {gghalves}

Points with jitter for half geoms.

Description

Points with jitter for half geoms.

Usage

geom_half_point(
  mapping = NULL,
  data = NULL,
  stat = "HalfPoint",
  position = "dodge2",
  ...,
  side = "r",
  transformation = position_jitter(),
  range_scale = 0.75,
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE
)

Arguments

mapping

Set of aesthetic mappings created by aes() or aes_(). If specified and inherit.aes = TRUE (the default), it is combined with the default mapping at the top level of the plot. You must supply mapping if there is no plot mapping.

data

The data to be displayed in this layer. There are three options:

If NULL, the default, the data is inherited from the plot data as specified in the call to ggplot().

A data.frame, or other object, will override the plot data. All objects will be fortified to produce a data frame. See fortify() for which variables will be created.

A function will be called with a single argument, the plot data. The return value must be a data.frame, and will be used as the layer data. A function can be created from a formula (e.g. ~ head(.x, 10)).

stat

The statistical transformation to use on the data for this layer, as a string.

position

Position adjustment, either as a string, or the result of a call to a position adjustment function.

...

Other arguments passed on to layer(). These are often aesthetics, used to set an aesthetic to a fixed value, like colour = "red" or size = 3. They may also be parameters to the paired geom/stat.

side

The side on which to draw the half violin plot. "l" for left, "r" for right, defaults to "l".

transformation

An evaluated 'position_*()' function yielding a 'Position' object with specified parameters to calculate the transformation of the points. Defaults to 'ggplot2::position_jitter()'.

range_scale

If no 'width' argument is specified in 'transformation', 'range_scale' is used to determine the width of the jitter. Defaults to '0.75', which is half of the allotted space for the jitter-points, whereas '1' would use all of the allotted space.

na.rm

If FALSE, the default, missing values are removed with a warning. If TRUE, missing values are silently removed.

show.legend

logical. Should this layer be included in the legends? 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 display.

inherit.aes

If 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. borders().

Examples

ggplot(iris, aes(x = Species, y = Petal.Width, fill = Species)) + 
  geom_half_point()
  
ggplot(iris, aes(x = Species, y = Petal.Width, fill = Species)) + 
  geom_half_point(side = "l")
