I'm currently trying to add labels to a map of US counties, that display the county name. I visualized the map using geom_sf
and everything works out fine. I specified some other things like the fill aesthetic etc. and it gets plottet like I wanted it to. But if I try to add labels via geom_sf_label
, I always get the following error: stat_sf_coordinates requires the following missing aesthetics: geometry
.
Here is the code that works:
df %>%
group_by(county_fips)%>%
count()%>%
full_join(geo_data, by = c("county_fips" = "fips")) %>%
ggplot(aes(fill = n))+
geom_sf(aes(geometry = geometry))+
scale_fill_continuous(low = "antiquewhite2", high = "palevioletred4", guide = "colorbar")+
theme_void()
My data cointains traffic stops in different counties in the US. I count them by county and visualize that in a choropleth map.
Here is how I tried to add the label:
df %>%
group_by(county_fips)%>%
count()%>%
full_join(geo_data, by = c("county_fips" = "fips")) %>%
ggplot(aes(fill = n))+
geom_sf(aes(geometry = geometry))+
geom_sf_label(aes(label = paste0(ID)))+
scale_fill_continuous(low = "antiquewhite2", high = "palevioletred4", guide = "colorbar")+
theme_void()
The join I used works out just fine. Only when it comes to the labels the above error is displayed. I tried to add the geometry aesthetic in geom_sf_label, too, but that won't work either. I hope someone can help me to find the mistake I made. Thank you in advance!
