Description

Contours from a 2d density estimate

Usage

geom_density2d(mapping=NULL, data=NULL, stat="density2d", position="identity", ...)

Arguments

mapping mapping between variables and aesthetics generated by aes
data dataset used in this layer, if not specified uses plot dataset
stat statistic used by this layer
position position adjustment used by this layer
... ignored

Details

Perform a 2D kernel density estimatation using kde2d and display the results with contours.

This page describes geom_density2d, see layer and qplot for how to create a complete plot from individual components.

Value

A layer

Aesthetics
