get child H3 cell indices
This function returns the children of a particular H3 cell at the requested resolution.
get_children(h3_address = NULL, res = NULL, simple = TRUE)
h3_address |
Character; 15-character index generated by H3. |
res |
Integer; Desired H3 resolution. See https://h3geo.org/docs/core-library/restable/ for allowable values and related dimensions. |
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 vector of H3 cell indexes.
The number of cells returned for each request is '7 ^ (parent_res - child_res)', so jumping three levels will return 343 indexes per request. This can cause memory issues with larger requests.
# What are the children of this resolution 6 cell index at resolution 8? get_children(h3_address = '86be8d12fffffff', res = 8)
