R: Format well-known geometry for printing

wk_format {wk} | R Documentation

## Format well-known geometry for printing

### Description

Provides an abbreviated version of the well-known text representation of a geometry. This returns a constant number of coordinates for each geometry, so is safe to use for geometry vectors with many (potentially large) features. Parse errors are passed on to the format string and do not cause this handler to error.

### Usage

    wk_format(handleable, precision = 7, trim = TRUE, max_coords = 6, ...)

    wkt_format_handler(precision = 7, trim = TRUE, max_coords = 6)

### Arguments

`handleable` | A geometry vector (e.g., `wkb()`, `wkt()`, `xy()`, `rct()`, or `sf::st_sfc()`) for which `wk_handle()` is defined.
`precision` | If `trim` is `TRUE`, the total number of significant digits to keep for each result or the number of digits after the decimal place otherwise.
`trim` | Use `FALSE` to keep trailing zeroes after the decimal place.
`max_coords` | The maximum number of coordinates to include in the output.
`...` | Passed to the `wk_handle()` method.

### Value

A character vector of abbreviated well-known text.

### Examples

    wk_format(wkt("MULTIPOLYGON (((0 0, 10 0, 0 10, 0 0)))"))
    wk_format(new_wk_wkt("POINT ENTPY"))
    wk_handle(
      wkt("MULTIPOLYGON (((0 0, 10 0, 0 10, 0 0)))"),
      wkt_format_handler()
    )
