Examples

tmap_ch <- tilemap_ch()
## Not run: 
require(sf)
require(tidyverse)

# cantonal label, as centroid of the tiles. Needs to be a simple (non-sf) object to be plotted as geom_text
tmap.label <- data.frame(label = as.character(tmap_ch$Name), tmap_ch %>% st_centroid() %>% st_coordinates())

# PLOT
tm_ch <- ggplot() + 
  geom_sf(data = tmap_ch) + 
  theme_map()

# add canton 2 letters labels
tm_ch + geom_text(data = tmap.label, aes(x = X, y = Y, label = label), hjust = 0.5, vjust = 0.5)

## Plot ballot map, Loi fédérale sur la radio et la télévision 5950
fballot_canton <- loadCantonsCHFederalBallot() 
vote <- fballot_canton[,which(colnames(fballot_canton) == "5950")] %>% enframe()
tmap_ch <- left_join(tmap_ch, vote, by = c("Name" = "name"))
ggplot() + 
  geom_sf(data = tmap_ch, aes(fill = value)) +
  theme_map() +
  # add canton 2 letters labels
   geom_text(data = tmap.label, aes(x = X, y = Y, label = label), hjust = 0.5, vjust = 0.5, colour = "white", size = 2.5)
