Get a donut of H3 cell indexes
This function returns all the H3 cell indexes at the specified step from the address supplied.
get_ring(h3_address = NULL, ring_size = 1, simple = TRUE)
h3_address |
Character; 15-character cell index generated by H3. |
ring_size |
Character; number of steps away from the central cell. Defaults to 1. |
simple |
Logical; whether to return a vector of outputs or a data frame containing both inputs and outputs. |
By default, a list of length(h3_address). Each list element contains a character vector of H3 cells belonging to that step away from the input address.
In total, the number of cells returned for each input index is 'ring_size \* 6'.
# What are the neighbours of this cell at step 2? get_ring(h3_address = '86be8d12fffffff', ring_size = 2)
