A5 Cell Index Vector

Create, test, and coerce A5 cell index vectors. Cells are stored as hex-encoded character strings.

Usage

a5_cell(x = character())

is_a5_cell(x)

as_a5_cell(x)

a5_is_cell(x)

Arguments

x

A character vector of hex-encoded A5 cell IDs, or an object coercible to one.

Value

An a5_cell vector (a5_cell, as_a5_cell), a logical scalar (is_a5_cell), or a logical vector (a5_is_cell).

Examples

cells <- a5_cell(c("0800000000000006", "0800000000000016"))
cells
#> <a5_cell[2]>
#> [1] 0800000000000006 0800000000000016
a5_is_cell(c("0800000000000006", "not_a_cell", NA))
#> [1]  TRUE FALSE    NA
