Is there a way to implement canvas as renderer in Leaflet R instead of SVG?

I need to plot >100k georreferenced points on a leaflet map I created with R. When plotting them with addCircleMarkers the map crashes on every browser.

Here it is suggested to replace SVG as the renderer so it doesn't create a DOM element for every data point, instead a Canvas layer. Nevertheless, I can't find the preferCanvas option in the addCircleMarkers function in R.

Does anyone know if this can be implemented in R?

Have you looked into `markerClusterOptions` in leaflet or `mapview` (also based on leaflet)? – MLavoie Mar 12 '18 at 12:45
Thanks MLavoie! Mapview apparently has a 'addLargeFeatures' function that does exactly that I think. I'll try it out and post back. Thanks again! – Santiago Esteban Mar 12 '18 at 23:24
