An R Interface to Leaflet Maps

Leaflet is an open-source JavaScript library for interactive maps. This R package makes it easy to create Leaflet maps from R.

library(leaflet)
m = leaflet() %>% addTiles()
m  # a map with the default OSM tile layer

m = m %>% setView(-93.65, 42.0285, zoom = 17)
m

m %>% addPopups(-93.65, 42.0285, 'Here is the <b>Department of Statistics</b>, ISU')
