hex_bin: Bin data into hexagons (2d).

In hadley/densityvis: Common interface to a range of density calculations.

Description

Bin data into hexagons (2d).

Usage

hex_bin(x, y, weight, width, height, xbins=20, ybins=20,
    na.rm=FALSE)

Arguments

x	a numeric vector of x positions
y	a numeric vector of y positions
weight	NULL or a numeric vector providing weights for each observation
height	height of each hexagon, if NULL computed from ybins
width	width of each hexagon, if NULL computed from ybins
xbins	number of horizontal bins, if width unspecified
ybins	number of vertical bins, if height unspecified
na.rm	If TRUE missing values will be silently removed, otherwise they will be removed with a warning.

Value

A data frame with columns x, y and freq, and attributes width and height.

See Also

hex_pos for algorithm that finds hexagon center closest to each point and hex_coord that generates coordinates of each hexagon.

Examples

plot(hex_bin(runif(1e4), runif(1e4)))
plot(hex_bin(rnorm(1e4), rnorm(1e4)))

data(baseball, package = "plyr")
bin <- hex_bin(baseball$g, baseball$ab)
