ggdensity: Grob function: 1d density Display a smooth density estimate.

In hadley/ggplot1: Before there was ggplot2

Grob function: 1d density Display a smooth density estimate.

Description

Aesthetic mappings that this grob function understands:

Usage

ggdensity(plot, aesthetics = list(), ..., data = NULL)

Arguments

plot	the plot object to modify
aesthetics	named list of aesthetic mappings, see details for more information
...	other options, see details for more information
data	data source, if not specified the plot default will be used

Details

• x:x position (required)

• weight: observation weights

These can be specified in the plot defaults (see ggplot) or in the aesthetics argument. If you want to modify the position of the points or any axis options, you will need to add a position scale to the plot. These functions start with ps, eg. pscontinuous or pscategorical

Other options:

• adjust: see density for details

• kernel: kernel used for density estimation, see density for details

• other aesthetic properties passed on to ggline

• weight: observation weights

Examples

library(ggplot2movies)
m <- ggplot(movies, aesthetics=list(x=rating))
ggdensity(m)

m <- ggplot(movies, Action ~ Comedy, aesthetics=list(x=rating), margins=TRUE)
ggdensity(m)
ggdensity(m, scale="freq")
ggdensity(m, colour="darkgreen", size=5)
