Create single shape made of coordinates

coo_single objects are tibble with exactly two columns named x and y. Anything that can be turned should work.

new_coo_single(x = tibble::tibble(x = double(), y = double()))

validate_coo_single(x)

coo_single(x)

is_coo_single(x)

is_coo_single1(x)

Arguments

x

anything that can be turned a tibble by tibble::tibble() should work

Value

a coo_single object

Details

You should use the helper coo_single, new_coo_single and validate_coo_single are for internal operations.

Functions

  • new_coo_single: Constructor

  • validate_coo_single: Validator

  • coo_single: Helper

  • is_coo_single: Class tester

  • is_coo_single1: Class1 tester

Examples

coo_single()
#> # A tibble: 0 x 2
#> # … with 2 variables: x <dbl>, y <dbl>
#> ❯coo_single with 0 coordinates
