This tutorial guides you through producing interactive maps using the leaflet package for R. These can then easily be customised and embedded into websites or other web based applications.
Download the Leaflet package
Create a basic map
mymap <- leaflet() %>% addTiles() %>% # Add default OpenStreetMap map tiles addMarkers(lng=-0.127949, lat=51.507752, popup="Add your description here") mymap
More map styles
mymap <- leaflet() %>% addTiles() %>% setView( lng=-0.127949, lat=51.507752, zoom = 5 ) %>% addProviderTiles("NASAGIBS.ViirsEarthAtNight2012") mymap
mymap <- leaflet() %>% addTiles() %>% setView( lng=-0.127949, lat=51.507752, zoom = 15 ) %>% addProviderTiles("Esri.WorldImagery") mymap
There are many more styles available at this link. Simply copy the name of the style and paste into the addProviderTiles line in the code above.
Note: some style only work up to a certain zoom level. For example, NASA’s Earth at Night style (as per the example above) does not work when fully zoomed in. Ensure you set the correct zoom level using setView in the code.
