This function creates a Voronoi diagram from a set of points. The result is added as a source to the map, which can then be styled using add_fill_layer(), etc.
Usage
turf_voronoi(
map,
layer_id = NULL,
data = NULL,
coordinates = NULL,
bbox = NULL,
property = NULL,
source_id,
input_id = NULL
)Arguments
- map
A mapboxgl, maplibre, mapboxgl_proxy, or maplibre_proxy object.
- layer_id
The ID of a layer or source containing points (mutually exclusive with data and coordinates).
- data
An sf object containing points (mutually exclusive with layer_id and coordinates).
- coordinates
A list of coordinate pairs list(c(lng,lat), c(lng,lat), ...) for multiple points (mutually exclusive with layer_id and data).
- bbox
Optional. Can be: (1) A numeric vector of length 4, in format `c(xmin, ymin, xmax, ymax)', (2) An sf object to extract bbox from, or (3) A layer_id string to extract bbox from and clip results to.
- property
Optional. Character string specifying a column name from the input points to transfer to the Voronoi polygons using spatial collection.
- source_id
The ID for the new source containing the Voronoi diagram. Required.
- input_id
Optional. Character string specifying the Shiny input ID suffix for storing results. If NULL (default), no input is registered. For proxy operations, the result will be available as
input[[paste0(map_id, "_turf_", input_id)]].
