stat_joy: Stat for density joyplots

Description

This stat is the default stat used by geom_joy. It is very similar to stat_density, however there are a few differences. Most importantly, the density bandwidth is chosen across the entire dataset.

Usage

stat_joy(mapping = NULL, data = NULL, geom = "joy",
  position = "identity", na.rm = FALSE, show.legend = NA,
  inherit.aes = TRUE, bandwidth = NULL, from = NULL, to = NULL, ...)

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.

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.

geom

The geometric object to use to display the data.

position

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

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.

inherit.aes

If FALSE, overrides the default aesthetics, rather than combining with them.

bandwidth

Bandwidth used for density calculation. If not provided, is estimated from the data.

from, to

The left and right-most points of the grid at which the density is to be estimated, as in density(). If not provided, there are estimated from the data range and the bandwidth.

...

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