Find optimal hexagonal cell size for target number of cells

Uses binary search to find the hexagonal cell size (flat-to-flat distance) that produces approximately the target number of hexagons.

Usage

find_hex_cell_size_for_target_cells(
  study_area,
  target_cells,
  cell_size_min = 0.001,
  cell_size_max = 10,
  tol = 0.05,
  max_iter = 20
)

Arguments

study_area

sf object (polygons)

target_cells

target number of hexagons

cell_size_min

minimum cell size to try (in map units)

cell_size_max

maximum cell size to try (in map units)

tol

tolerance for convergence (fraction of target_cells)

max_iter

maximum iterations for binary search

Value

cell size (flat-to-flat distance) that gives closest to target_cells hexagons
