stat_bin2d {ggplot2}R Documentation

stat_bin2d

Description

Bin 2d plane into rectangles

Usage

stat_bin2d(mapping=NULL, data=NULL, geom="rect", position="identity", bins=30, drop=TRUE, ...)

Arguments

mapping mapping between variables and aesthetics generated by aes
data dataset used in this layer, if not specified uses plot dataset
geom geometric used by this layer
position position adjustment used by this layer
bins NULL
drop NULL
... ignored

Details

This page describes stat_bin2d, see layer and qplot for how to create a complete plot from individual components.

Value

A layer

Aesthetics

The following aesthetics can be used with stat_bin2d. Aesthetics are mapped to variables in the data with the aes function: stat\_bin2d(\code{aes}(x = var))

Examples

## Not run: 
d <- ggplot(diamonds, aes(carat, price))
d + stat_bin2d()
d + geom_bin2d()

# You can control the size of the bins by specifying the number of
# bins in each direction:
d + stat_bin2d(bins = 10)
d + stat_bin2d(bins = 30)

# Or by specifying the width of the bins
d + stat_bin2d(binwidth = c(1, 1000))
d + stat_bin2d(binwidth = c(.1, 500))

# Or with a list of breaks
x <- seq(min(diamonds$carat), max(diamonds$carat), by = 0.1)
y <- seq(min(diamonds$price), max(diamonds$price), length = 50)
d + stat_bin2d(breaks = list(x = x, y = y))

# With qplot
qplot(x, y, data = diamonds, geom="bin2d", 
  xlim = c(4, 10), ylim = c(4, 10))
qplot(x, y, data = diamonds, geom="bin2d", binwidth = c(0.1, 0.1),
  xlim = c(4, 10), ylim = c(4, 10))
