Plots

This package doesn’t provide any plot functions, but since objects are sf, it is pretty straigtforward to plot them either using ggplot2 or leaflet.

# Using ggplot2
library(ggplot2)
library(sf)
#> Linking to GEOS 3.6.1, GDAL 2.3.2, PROJ 4.9.3
ggplot() + 
  geom_sf(data = cartofr[["region"]]) + 
  geom_sf_label(aes(label = name_fr), data = suppressWarnings(st_centroid(cartofr[["region"]])), size = 2.5) + 
  theme_void()
#> Warning: Removed 6 rows containing missing values (geom_label).

# Using leaflet
library(leaflet)
cartofr[["dept"]] %>% 
  leaflet() %>%
  addProviderTiles("CartoDB.Positron") %>% 
  addPolygons(label = ~name_fr, color = "gray", opacity = 1, fillOpacity = 0, weight = 2)
