buffer_points_linear: Buffer points linear

In crazycapivara/h3forr: An R Interface to H3

Description

Weight is calculated as 1 - distance / (1 + radius).

Usage

buffer_points_linear(points, radius = 2, res = 8)

Arguments

points	matrix, data frame or object of class sf with POINT geometry
radius	number of rings (used as buffer around points)
res	resolution of hexagons to return

Examples

library(sf)
library(leaflet)

bart_stations <- system.file("geojson/bart_stations.geojson", package = "h3forr") %>%
  st_read(quiet = TRUE)

buffer <- buffer_points_linear(bart_stations, radius = 2, res = 8)
hexagons <- h3_to_geo_boundary(buffer$h3_index) %>% geo_boundary_to_sf()

pal <- colorNumeric("Blues", buffer$norm)

map <- leaflet() %>% addTiles() %>%
  addPolygons(
    data = hexagons,
    fillOpacity = 0.9,
    fillColor = pal(buffer$norm),
    weight = 1,
    color = "white",
    label = sprintf("%s", buffer$norm)
  ) %>%
  addMarkers(data = bart_stations)

if (interactive()) map
