Display a smooth density estimate.

Usage

geom_density(mapping = NULL, data = NULL, stat = "density", position = "identity", 
  na.rm = FALSE, ...)

Arguments

mapping
The aesthetic mapping, usually constructed with aes or aes_string. Only needs to be set at the layer level if you are overriding the plot defaults.
data
A layer specific dataset - only needed if you want to override the plot defaults.
stat
The statistical transformation to use on the data for this layer.
position
The position adjustment to use for overlappling points on this layer
na.rm
If FALSE (the default), removes missing values with a warning. If TRUE silently removes missing values.
...
other arguments passed on to layer. This can include aesthetics whose values you want to set, not map. See layer for more details.
