Can't run Leaflet.markercluster with Shiny-server

[withr]

Hi Danzel, First, thanks a lot for creating this amazing package!! I found many sites are using it after I have chosen it. Today, I spent almost a whole day to integrate it with Shiny-server, which is a server for hosting R based application. In my app, I used rCharts (a R package which support creating Leaflet map) for its Leaflet class. https://github.com/ramnathv/rCharts/blob/master/R/Leaflet.R. Everything goes fine, except markercluaster doesn't work.

I used the data and code in: http://leaflet.github.io/Leaflet.markercluster/example/marker-clustering-realworld.388.html, and got error message said: TypeError: undefined is not a function

I run the following code in Chrome's console: var markers = L.markerClusterGroup();
for (var i = 0; i < addressPoints.length; i++) { var a = addressPoints[i]; var title = a[2]; var marker = L.marker(new L.LatLng(a[0], a[1]), { title: title }); marker.bindPopup(title); markers.addLayer(marker); } and there is no error message.
But when run: map.addLayer(markers); I will get that error the first time, but not at the second time (however, still can't find the cluster markers).

Here is the address of my app: http://188.226.199.99/shiny-map

Any kind of help will be greatly appreciated.

Regards!

Run it under the javascript debugger and see what is undefined. You should be able to figure out what to do from there. You probably aren't including something you need to.

var tNormM = L.tileLayer.chinaProvider('TianDiTu.Normal.Map', {maxZoom:18,minZoom:4}); L.tileLayer.chinaProvider === undefined and you call it as function so its throws error.

Hope it helps.

@FalloutPL Sorry for my mistake (I changed some files today, and you happen to visit the website at that time). Now, I have corrected all files. please have a look.

@danzel I guess I have everything included, because I can run it without Shiny-server, I guess may some leaflet functions, or variables were blocked by shiny.js,
