# create some polygons, in this case convex hulls
sp <- split(crotalus, crotalus$genSp)
sp <- lapply(sp, function(x) x[,c('decimallongitude','decimallatitude')])
sp <- lapply(sp, function(x) x[chull(x),])
poly <- lapply(sp, function(x) 
	sf::st_convex_hull(sf::st_combine(sf::st_as_sf(x, coords = 1:2, crs = 4326))))
