mapboxer: An R Interface to Mapbox GL JS

Mapboxer makes Mapbox GL JS, an open source JavaScript library that uses WebGL to render interactive maps, available within R via the htmlwidgets package.

Installation

Install the release version from CRAN with:

install.packages("mapboxer")

Install the development version from GitHub with:

# install.packages("remotes")
remotes::install_github("crazycapivara/mapboxer")

Usage

library(mapboxer)

map <- motor_vehicle_collisions_nyc %>%
  dplyr::mutate(
    color = ifelse(injured == 0, "yellow", "red")
  ) %>%
  as_mapbox_source() %>%
  mapboxer(
    center = c(-73.9165, 40.7114),
    zoom = 10
  ) %>%
  add_navigation_control() %>%
  add_circle_layer(
    circle_color = c("get", "color"),
    circle_blur = 1,
    circle_stroke_color = "red",
    circle_stroke_width = 1,
    popup = "<p>{{date}} {{time}}</p><p>Number of persons injured: {{injured}}</p>"
  )

if (interactive()) map

By default mapboxer uses Carto vector styles as basemaps. It is also possible to use raster tiles or a background color.

If you want to use styles from Mapbox it is recommended that you store your API token in an environment vatiable called MAPBOX_API_TOKEN.
