ggplot2를 사용하여 세계지도를 플롯하려고합니다. 다음은 지금까지 내가 가지고있는 것입니다 :ggplot2 + 세계지도 = 이전 데이터?
library(ggplot2)
world <- map_data("world")
ggplot(aes(long, lat, group=group), data=world) + geom_polygon()
이것은 잘 작동하며 쉽게 수행 할 수 있습니다. 불행히도, 세계지도 데이터는 오래된 것 같습니다. 예를 들어, 싱가포르와 체코 같은 국가는 사라지고 대신 소련과 같은 지역이 있습니다. 세계지도 데이터를 최신 상태로 유지하는 방법에 대해 알고 싶습니다.
