Swapping Popups for Labels

Popups are great, but they require a little extra effort. That is when labels come to our aid. Using the label argument in the addCircleMarkers() function we can get more information about one of our markers with a simple hover!

ipeds %>% 
    leaflet()  %>% 
    addProviderTiles("CartoDB")  %>% 
    addCircleMarkers(label = ~name, radius = 2)

Labels are especially helpful when mapping more than a few locations as they provide quick access to detail about what each marker represents.
