R/fortify_hexagon.R
fortify_hexagon.RdCreates the points that define a hexagon polygon for plotting
fortify_hexagon(data, sf_id, hex_size)a data frame created by the allocate function
a string to indicate the column to identify individual polygons
a float value in degrees for the diameter of the hexagons
a data frame of the seven points used to draw a hexagon
# same column is used in create_centroids
fortify_hexagon(data = tas_lga_hexctr, sf_id = "lga_code_2016", hex_size = 0.2)
