Reduce a set of H3 indices of the same resolution to the minimum number of H3 indices of varying resolution that entirely covers the input area.

compact_cells(x)

uncompact_cells(x, resolution)

Arguments

x

a vector of H3 indexes.

resolution

a scalar integer representing the grid resolution in the range [0, 15].

Examples

y <- uncompact_cells(x, 5)[[1]]
z <- compact_cells(y)
all.equal(x, z)
#> [1] TRUE
