Is there a way to disable the double click zoom in Leaflet for R?

I've created a Shiny app that changes polygon styles when a country's region is clicked on/off. If you select and immediately deselect the same polygon, the map zooms in. I want to disable this feature so that there's no wonky zooming!

According to leaflet.js documentation, you can disable this feature in JavaScript. Leaflet for R refers to this documentation when I try to search for the solution within R, which is completely unhelpful.


There is the option doubleClickZoom = FALSE :

leaflet(data,options = leafletOptions(doubleClickZoom= FALSE)) %>% ...

Other options can be found here : Disable leaflet interaction temporary

I didn't find an option to disable the double click zoom in the R leaflet package. So I tried to disable this option by passing JavaScript code as strings to the shiny web app.

You can try the reproducible example below.


#  Make Leaflet map with JavaScript

# // Leaflet providers
leafletProviders <- "var OpenStreetMap_Mapnik = L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
                                                maxZoom: 19
# // Map definition
map <- "var map = L.map('map', {
                  center: [-34.7247, -56.1237],
                  zoom: 8,
                  layers: [OpenStreetMap_Mapnik]

# // Basemaps
baseMaps <- "var baseMaps = {'OpenStreetMap': OpenStreetMap_Mapnik};"

# // Add a layer control element to the map
layerControl <- "layerControl = L.control.layers(baseMaps, null, {
                                position: 'topleft'});

ui <- fluidPage(

  HTML(paste("<script>", "\n", leafletProviders, "\n", map, "\n", baseMaps, "\n", layerControl,"\n", "</script>", sep = "")), # Make map JS code 
  HTML("<div id='divHtml' class='shiny-html-output'></div>") # Create empty div with known ID

server <- function(input, output, session) {

  output$divHtml <- renderUI({

    interaction <- "map.doubleClickZoom.disable();" # Modify interaction with map
    mapHtml <- HTML(paste("<script>", interaction, "</script>", sep = "")) # Put JS code for interaction with created map in created DIV element




shinyApp(ui, server)
