is_nb: H3 index neighbors

In h3o: H3 Geospatial Indexing System

H3 index neighbors

Description

Test if two H3 cells are neighbors.

Usage

is_nb_pairwise(x, y)

is_nb_sparse(x, y)

Arguments

x	an H3 vector.
y	and H3 vector.

Value

is_nb_pairwise() returns a logical vector wheraas is_nb_sparse() returns a list with logical vector elements.

Examples

cells_ids <-c(
  "85e22da7fffffff", "85e35ad3fffffff",
  "85e22daffffffff", "85e35adbfffffff",
  "85e22db7fffffff", "85e35e6bfffffff",
  "85e22da3fffffff"
)

cells <- h3o::h3_from_strings(cells_ids)

is_nb_pairwise(cells, rev(cells))
is_nb_sparse(cells, cells)
