This post is a step-by-step tutorial leading to the following choropleth map. (circles, rectangles, polygons, ...), or other map elements, comma-separated list of WMS layers to show, a numeric vector of longitudes, or a one-sided formula of the form lng1, Both leaflet() and the map layers have an optional data parameter that is designed to receive spatial data with the following formats: Base R The arguments of all layers take normal R objects : Use the arguments of addPolygons() to map the high income zip codes in NC with: . color = "#03F", attribution = NULL, clusterOptions = NULL, Not sure that it is the right place for my question, but did not find anything better. layers (e.g. popupOptions = NULL, I used clustered circle markers with a number label associated with the count of squirrels to make the data points more readable. initially, but can be overridden, the attribution text of the tile layer (HTML). fillOpacity = 0.2, dashArray = NULL, The labelOptions argument can be populated using the labelOptions() function.
