In crazycapivara/h3forr: An R Interface to H3

Description Usage Arguments Value Note Examples

Get all hexagons in a k-ring around a given center ordered by distance from the origin.

1	k_ring_distances(h3_index, ring_size = 1)

`h3_index`	character vector representing H3 indexes
`ring_size`	number of rings

data frame with columns h3_index and distance (ring number); list of data frames if multiple centers are supplied

The order of the hexagons within each ring is undefined.
