Create Interactive Graphs using Leaflet:

library(leaflet)
basins <- getBasin(sites)
Range=c(-81,-73,38,44)
flowLines <- getFlowLines(Range, streamorder = 5)

leaflet() %>% 
  addProviderTiles("CartoDB.Positron") %>% 
  setView(-78, 41, zoom = 6) %>%
  addPolygons(data=basins, weight=2, color = "grey") %>%
  addPolylines(data=flowLines, weight=1) %>%
  addCircleMarkers(siteInfo$dec_long_va,siteInfo$dec_lat_va,
                   color = "red",
                   radius=4,
                   stroke=FALSE,
                   fillOpacity = 0.8, opacity = 0.8,
                   popup=siteInfo$station_nm)
