Helper functions to convert between different hexagon measurements.
For a regular hexagon, the circumradius equals the edge length, so the
"edge" and "circumradius" helpers are mathematically identical (provided
for clarity at the call site).
Usage
hex_flat_to_edge(flat_to_flat)
hex_flat_to_circumradius(flat_to_flat)
hex_edge_to_flat(edge_length)
hex_circumradius_to_flat(circumradius)
Arguments
- flat_to_flat
Flat-to-flat distance (between opposite edges).
- edge_length
Edge length of the hexagon.
- circumradius
Circumradius (centre to vertex).
Value
Numeric value in the same units as the input.
Details
- `hex_flat_to_edge()`: flat-to-flat distance to edge length
- `hex_flat_to_circumradius()`: flat-to-flat distance to circumradius
- `hex_edge_to_flat()`: edge length to flat-to-flat distance
- `hex_circumradius_to_flat()`: circumradius to flat-to-flat distance
Examples
hex_flat_to_edge(1000) # ~577.35
#> [1] 577.3503
hex_flat_to_circumradius(1000) # ~577.35
#> [1] 577.3503
hex_edge_to_flat(577.35) # ~1000
#> [1] 999.9995
hex_circumradius_to_flat(577.35)# ~1000
#> [1] 999.9995
