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

Description

Generate hexagon coordinates.

Usage

hex_coord(x, y, width, height)

Arguments

x	horizontal position of center
y	vertical position of center
width	hex width
height	hex height

Details

Long axis is horizontal. Edges clock-wise from far-left, separated by row of missing values.

Value

A two column matrix with 7 times as many rows as input.

Examples

x <- runif(1000)
y <- runif(1000)
res <- unique(hex_pos(x, y, 0.5, 0.5))
hexes <- hex_coord(res[, 1], res[, 2], 0.5, 0.5)

plot(hexes, type = "n")
polygon(hexes)
points(res)
