[R] No map background showed up when adding tile in leaflet()

[Lin, Ye]

Hey All,

I am learning to create a map with leaflet(), but my default map background won't show up, its just grey.

Here is my code:

leaflet() %>% addTiles()
addCircleMarkers(lng=points$lon,lat=points$lat,
                         radius=6,stroke=FALSE,fillOpacity = 0.5)

When I run the code, the markers show up and interaction of zoom in/out works okay, but background is always solid grey, not sure why. I tried "addProviderTiles("Stamen.TonerLabels")" as well, does not work out.

Thanks for your help in advance.
