Get width of hexagon given height

Description

Get width of hexagon given height

Usage

hex_wd(height)

Arguments

height

scaler

Details

For use with ggplot and geom_hex binwidth arguments, which expects arguments in width/height. I want hexagons in maps to be a specific area. See this blog post for a specific use case with ggplot.

Value

A scaler for the width

Examples

area_check <- 1000
wh <- hex_dim(area_check^2)   #e.g. a square kilometer if spatial units are in meters
area <- hex_area(wh[1]/2)       #inverse operation
all.equal(area_check,sqrt(area))
wi <- hex_wd(wh[1])
all.equal(wh[2],wi)
