There is a empty space on the map. The data is ivalable for those regions. What could be the Problem?
Geo Data for Germany:
URL <- "https://biogeo.ucdavis.edu/data/gadm3.6/Rsp/gadm36_DEU_1_sp.rds"
germany <- readRDS(url(URL))
germany <- fortify(germany)
df_Karte_ratio %>%
ggplot(aes(x = long, y = lat,
group = group, fill = ratio_fl_arzt
))+
geom_polygon(col = "black") +
coord_map()+
facet_grid(~EP01_KJP02_BEIDE03_PSM_04_20)+
labs(title = "Fälle-Arzt Verhältnis")+
theme_map()+
theme(
legend.position = "right",
#legend.direction = "horizontal",
legend.title = element_blank())+
scale_fill_continuous_sequential(palette = "BluYl")
Sadly I could not find any information about this issue
