These are some simple, early maps I created with RStudio, rendered in Leaflet.js.
The above map, produced in R's Tmap library, shows eelgrass coverage in Maine’s Casco Bay as of 2018, based on a Maine Department of Environmental Protection dataset and styled with Esri’s World Street Map and a palette of shades of green.
R Code Used:
> eelgrassdata<-st_read("MaineDEP_-_Eelgrass_2018_(Casco_Bay_Only).shp")
>tm_basemap("Esri.WorldStreetMap")+tm_shape(eelgrassdata)+tm_fill("Cover_Pct", palette="Greens")
