Add an editor

Lets the reader change the features on the map - move them, retype their attributes, add and delete. Edits happen in the browser and arrive in Shiny as input$<output_id>$edits; nothing is written back to the data frame the layer came from unless R does it.

Usage

add_editor(
  map,
  position = NULL,
  expand = FALSE,
  hide_create_features_section = NULL,
  sync_view_selection = NULL,
  ...
)

Arguments

map

Defines which map or arc_map_proxy() to modify.

position

default NULL. Defines which corner it sits in, one of "top-left", "top-right", "bottom-left", "bottom-right", or the direction-aware "top-start", "top-end", "bottom-start", "bottom-end". Each widget has its own default.

expand

default FALSE. Defines whether the widget is collapsed behind a button rather than drawn open. Worth it for the panels - the legend, layer list, basemap gallery - which otherwise cover the map. Collapsed widgets sharing a corner close each other when opened.

hide_create_features_section

default NULL. Defines whether the "add a feature" half of the panel is hidden, leaving editing only.

sync_view_selection

default NULL. Defines whether the editor and the map share one selection.

...

Named properties of the component itself, written either snake_case or camelCase. map_widgets() lists what each one takes.

Value

map, with the widget added.

Examples

arc_map() |> add_editor(position = "top-right")
