hex_dim {ptools}

Get dimensions of hexagon given area

Description

Get dimensions of hexagon given area

Usage

hex_dim(area)

Arguments

area

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 vector with two elements, first element is the height (vertex to vertex), the second element is the width (side to side)

See Also

hex_wd() for estimating the width given the height hex_area() for estimating the area given side length

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)
