Apply funciton for 2D rectangular bins.

Apply function for 2D rectangular bins.

Usage
stat_summary2d(mapping = NULL, data = NULL, geom = NULL,
    position = "identity", bins = 30, drop = TRUE,
    fun = mean, ...)
Arguments
bins
see stat_bin2d
drop
drop if the output of fun is NA.
fun
function for summary.
...
parameters passed to fun
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.
geom
The geometric object to use display the data
position
The position adjustment to use for overlappling points on this layer
Aesthetics

[results=rd,stage=build]{ggplot2:::rd_aesthetics("stat", "summary2d")}

stat_summary2d is 2D version of stat_summary. The data are devided by x and y. z in each cell is passed to arbitral summary function.

stat_summary2d requires the following aesthetics:

  • x: horizontal position
  • y: vertical position
  • z: value passed to the summary function

d <- ggplot(diamonds, aes(carat, depth, z = price)) d + stat_summary2d()

# Specifying function d + stat_summary2d(fun = function(x) sum(x^2)) d + stat_summary2d(fun = var)

stat_summary_hex for hexagonal summarization. stat_bin2d for the binning options.
