stat_summary_hex

From ggplot2 v1.0.1 by Hadley Wickham

Apply funciton for 2D hexagonal bins.

Apply function for 2D hexagonal bins.

Usage

stat_summary_hex(mapping = NULL, data = NULL, geom = "hex",
  position = "identity", bins = 30, drop = TRUE, fun = mean, ...)

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.
geom: The geometric object to use display the data
position: The position adjustment to use for overlappling points on this layer
bins: see stat_binhex
drop: drop if the output of fun is NA.
fun: function for summary.
...: parameters passed to fun

Aesthetics

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

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

stat_summary-hex 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_summary_hex()

# Specifying function d + stat_summary_hex(fun = function(x) sum(x^2)) d + stat_summary_hex(fun = var, na.rm = TRUE)

stat_summary2d for rectangular summarization. stat_bin2d for the hexagon-ing options.
