geom_violin: Violin plot.

Description

Violin plot.

Usage

geom_violin(mapping = NULL, data = NULL, stat = "ydensity",
  draw_quantiles = NULL, position = "dodge", trim = TRUE,
  scale = "area", na.rm = FALSE, show.legend = NA, inherit.aes = TRUE,
  ...)
stat_ydensity(mapping = NULL, data = NULL, geom = "violin",
  position = "dodge", adjust = 1, kernel = "gaussian", trim = TRUE,
  scale = "area", 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), is combined with the default mapping at the top le

data

A data frame. If specified, overrides the default data frame defined at the top level of the plot.

draw_quantiles

If not(NULL) (default), draw horizontal lines at the given quantiles of the density estimate.

position

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

trim

If TRUE (default), trim the tails of the violins to the range of the data. If FALSE, don't trim the tails.

scale

if "area" (default), all violins have the same area (before trimming the tails). If "count", areas are scaled proportionally to the number of observations. If "width", all violins have the same maximum width.

na.rm

If FALSE (the default), removes missing values with a warning. If TRUE silently removes missing values.

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.

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.

...

other arguments passed on to layer. There are three types of arguments you can use here:

• Aesthetics: to set an aesthetic to a fixed value, likecolor = "red"orsize = 3.

geom, stat

Use to override the default connection between geom_violin and stat_ydensity.

adjust

kernel
