Prepare cluster options for circle layers

This function creates a list of options for clustering circle layers.

Usage

cluster_options(
  max_zoom = 14,
  cluster_radius = 50,
  color_stops = c("#51bbd6", "#f1f075", "#f28cb1"),
  radius_stops = c(20, 30, 40),
  count_stops = c(0, 100, 750),
  circle_blur = NULL,
  circle_opacity = NULL,
  circle_stroke_color = NULL,
  circle_stroke_opacity = NULL,
  circle_stroke_width = NULL
)

Arguments

max_zoom

The maximum zoom level at which to cluster points.

cluster_radius

The radius of each cluster when clustering points.

color_stops

A vector of colors for the circle color step expression.

radius_stops

A vector of radii for the circle radius step expression.

count_stops

A vector of point counts for both color and radius step expressions.

circle_blur

Amount to blur the circle.

circle_opacity

The opacity of the circle.

circle_stroke_color

The color of the circle's stroke.

circle_stroke_opacity

The opacity of the circle's stroke.

circle_stroke_width

The width of the circle's stroke.

Value

A list of cluster options.

Examples

cluster_options(
    max_zoom = 14,
    cluster_radius = 50,
    color_stops = c("#51bbd6", "#f1f075", "#f28cb1"),
    radius_stops = c(20, 30, 40),
    count_stops = c(0, 100, 750),
    circle_blur = 1,
    circle_opacity = 0.8,
    circle_stroke_color = "#ffffff",
    circle_stroke_width = 2
