Add a vector tile layer from a TileJSON endpoint

Usage

add_vector_tiles(
  map,
  url,
  name = "Vector Tiles",
  source_layers = NULL,
  source_layer = NULL,
  style = list(),
  visible = TRUE,
  opacity = 1,
  ...
)

Arguments

map: A GeoLibre widget.
url: TileJSON endpoint for the vector tileset.
name: Layer name.
source_layers: Source layer names to render, for multi-layer tilesets.
source_layer: A single source layer name, for the common single-layer case. Ignored when source_layers is supplied.
style: Named list of GeoLibre style overrides such as fillColor, strokeColor, and strokeWidth.
visible: Whether the layer is initially visible.
opacity: Layer opacity from zero to one.
...: Additional style overrides given as named arguments, merged into style. add_geojson(map, data, fillColor = "red") and add_geojson(map, data, style = list(fillColor = "red")) are equivalent.

Value

The modified widget.

Examples

map <- geolibre() |>
  add_vector_tiles("https://example.com/tiles.json", source_layer = "roads")
stopifnot(map$x$project$layers[[1]]$type == "vector-tiles")
