wk_linestring: Create lines, polygons, and collections

In wk: Lightweight Well-Known Geometry Parsing

Create lines, polygons, and collections

Description

Create lines, polygons, and collections

Usage

wk_linestring(handleable, feature_id = 1L, ..., geodesic = NULL)

wk_polygon(handleable, feature_id = 1L, ring_id = 1L, ..., geodesic = NULL)

wk_collection(
  handleable,
  geometry_type = wk_geometry_type("geometrycollection"),
  feature_id = 1L,
  ...
)

wk_linestring_filter(handler, feature_id = 1L)

wk_polygon_filter(handler, feature_id = 1L, ring_id = 1L)

wk_collection_filter(
  handler,
  geometry_type = wk_geometry_type("geometrycollection"),
  feature_id = 1L
)

Arguments

handleable	A geometry vector (e.g., wkb(), wkt(), xy(), rct(), or sf::st_sfc()) for which wk_handle() is defined.
feature_id	An identifier where changes in sequential values indicate a new feature. This is recycled silently as needed.
...	Passed to the wk_handle() method.
geodesic	Use TRUE or FALSE to explicitly force the geodesic-ness of the output.
ring_id	An identifier where changes in sequential values indicate a new ring. Rings are automatically closed. This is recycled silently as needed.
geometry_type	The collection type to create.
handler	A wk_handler object.

Value

An object of the same class as handleable with whose coordinates have been assembled into the given type.

Examples

wk_linestring(xy(c(1, 1), c(2, 3)))
wk_polygon(xy(c(0, 1, 0), c(0, 0, 1)))
wk_collection(xy(c(1, 1), c(2, 3)))
