Description

Interactively Edit a Map

Usage

editMap(x, ...)
# S3 method for leaflet
editMap(
  x = NULL,
  targetLayerId = NULL,
  sf = TRUE,
  ns = "mapedit-edit",
  record = FALSE,
  viewer = shiny::paneViewer(),
  crs = 4326,
  title = "Edit Map",
  editor = c("leaflet.extras", "leafpm"),
  editorOptions = list(),
  ...
)
# S3 method for mapview
editMap(
  x = NULL,
  targetLayerId = NULL,
  sf = TRUE,
  ns = "mapedit-edit",
  record = FALSE,
  viewer = shiny::paneViewer(),
  crs = 4326,
  title = "Edit Map",
  editor = c("leaflet.extras", "leafpm"),
  editorOptions = list(),
  ...
)
# S3 method for `NULL`
editMap(x, editor = c("leaflet.extras", "leafpm"), editorOptions = list(), ...)

Value

sf simple features or GeoJSON

Arguments

x

leaflet or mapview map to edit

...

other arguments for leafem::addFeatures() when using editMap.NULL or selectFeatures

targetLayerId

string name of the map layer group to use with edit

sf

logical return simple features. The default is TRUE. If sf = FALSE, GeoJSON will be returned.

ns

string name for the Shiny namespace to use. The ns is unlikely to require a change.

record

logical to record all edits for future playback.

viewer

function for the viewer. See Shiny viewer. NOTE: when using browserViewer(browser = getOption("browser")) to open the app in the default browser, the browser window will automatically close when closing the app (by pressing "done" or "cancel") in most browsers. Firefox is an exception. See Details for instructions on how to enable this behaviour in Firefox.

crs

see st_crs.

title

string to customize the title of the UI window. The default is "Edit Map".

editor

character either "leaflet.extras" or "leafpm"

editorOptions

list of options suitable for passing to either leaflet.extras::addDrawToolbar or leafpm::addPmToolbar.

Details

When setting viewer = browserViewer(browser = getOption("browser")) and the systems default browser is Firefox, the browser window will likely not automatically close when the app is closed (by pressing "done" or "cancel"). To enable automatic closing of tabs/windows in Firefox try the following:

• input "about:config " to your firefox address bar and hit enter

• make sure your "dom.allow_scripts_to_close_windows" is true

Examples

if (FALSE) {
library(leaflet)
library(mapedit)
editMap(leaflet() %>% addTiles())
}
if (FALSE) {
  # demonstrate Leaflet.Draw on a layer
  library(sf)
  library(mapview)
  library(leaflet.extras)
  library(mapedit)

  # ?sf::sf
  pol = st_sfc(
    st_polygon(list(cbind(c(0,3,3,0,0),c(0,0,3,3,0)))),
    crs = 4326
  )
  mapview(pol) %>%
    editMap(targetLayerId = "pol")

  mapview(franconia[1:2,]) %>%
    editMap(targetLayerId = "franconia[1:2, ]")
}
