Я пытаюсь построить карту мира, используя ggplot2. Вот что я до сих пор:
library(ggplot2)
world <- map_data("world")
ggplot(aes(long, lat, group=group), data=world) + geom_polygon()
Это хорошо работает и легко сделать. К сожалению, данные по карте мира кажутся старыми. Например, такие страны, как Сингапур и Чехия, отсутствуют, и вместо этого существуют такие регионы, как СССР. Любая идея, как я могу получить более современные данные о карте мира?
