icon rotation in leaflet package

Question

I\'m learning to program in R with the leaflet package. I want to give an angle to the icons, and am trying it with this code:

m <- leaflet()
m <- ad

For your first point, I've found that you can load your image if it's stored in a directory named www.

|
|- app.R
|- www
    |- icon_plane.pg

Then you'll be able to load it with this piece of code

onRender("function(el, x) {
          var planeIcon = L.icon({iconUrl: 'icon_plane.png', iconAnchor:[16, 16]});
          var pathPattern = L.marker([34.45, 127.07], {icon: planeIcon, rotationAngle: 90}).addTo(this);
          }")

Becareful of loading correctly your js file. I spent a lot of time looking why my image wasn't showing and finally it was only because my script wasn't in the correct place.
