Usage

get_queried_features(map)

Value

An sf object containing the queried features, or an empty sf object if no features were found

Arguments

map

A map object (mapboxgl, maplibre) or proxy object (mapboxgl_proxy, maplibre_proxy, mapboxgl_compare_proxy, maplibre_compare_proxy)

Examples

if (FALSE) {
# In a Shiny server function:
observeEvent(input$query_button, {
    proxy <- maplibre_proxy("map")
    query_rendered_features(proxy, layer_id = "counties")
    features <- get_queried_features(proxy)
    print(nrow(features))
})
