Resizing custom markers in Leaflet for R

I am interested in making custom icons while using Leaflet in R.

The documentation has a nice example, but when experimenting with it, I realized that there is no way to allow the custom marker to resize when the map changes size.

Since size is one of the parameters and is fixed (iconWidth = 38, iconHeight = 95,), obviously the marker will stay consistently sized as zoom changes for map beneath it.

greenLeafIcon <- makeIcon(
  iconUrl = "http://leafletjs.com/docs/images/leaf-green.png",
  iconWidth = 38, iconHeight = 95,
  iconAnchorX = 22, iconAnchorY = 94,
  shadowUrl = "http://leafletjs.com/docs/images/leaf-shadow.png",
  shadowWidth = 50, shadowHeight = 64,
  shadowAnchorX = 4, shadowAnchorY = 62
)

Are there any hacks / ideas / protocols for having custom icons resize along with zoom?

That question is for Leaflet in JavaScript as opposed to the package written in R. – tumultous_rooster Aug 15 '15 at 16:52
the package in R wraps the Leaflet JavaScript and that solution is what you'll need to do to modify the size. You can add arbitrary JS functions to an R leaflet map. – hrbrmstr Aug 15 '15 at 16:53
So my question should have been, 'How do I wrap JavaScript code in R such that I can use it in the Leaflet package to resize my custom markers'! :-) – tumultous_rooster Aug 15 '15 at 16:59

Still no solution for the R package? – F. Privé May 29 '17 at 13:02
