hex_area | R Documentation |
The length of the side is half of the length from vertex to vertex (so height in geom_hex
).
hex_area(side)

scaler |
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.
A scaler for the width
hex_wd()
for estimating the width given the height
hex_dim()
for estimating width/height given area
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)
