Show, hide, or fade a layer that is already drawn — set_layer • arcgisviz

Changes one layer's appearance without resending it. remove_layer() takes it off the map instead.

Usage

set_layer(proxy, layer, visible = NULL, opacity = NULL)

remove_layer(proxy, layer = NULL)

Arguments

proxy: Defines which arc_map_proxy() to modify.
layer: Defines which layer, by the name it was added with. remove_layer() accepts NULL to remove every layer.
visible: default NULL. Defines whether the layer is drawn.
opacity: default NULL. Defines the layer opacity, from 0 to 1.

Value

proxy, invisibly.

Examples

if (interactive()) {
  arc_map_proxy("map") |>
    set_layer("Counties", visible = FALSE)
}
