Position of a layer in the draw order

Usage

find_layer_index(x, name)

Arguments

x: A GeoLibre widget or a project list.
name: A layer id or layer name.

Value

The one-based index of the first matching layer, or -1 when none matches. Unlike the functions that modify a layer, a name several layers share resolves to the first of them rather than raising.

Examples

map <- geolibre() |> add_marker(-77, 39, name = "Pin")
find_layer_index(map, "Pin")
#> [1] 1
find_layer_index(map, "Missing")
#> [1] -1
