Ответ 1
Вот решение с последней версией ggplot2
и ggtree
:
library(maps)
library(mapproj)
library(ggplot2)
library(ggtree)
library(dplyr)
library(magrittr)
world = map_data("world")
p <- ggplot(data=world, aes(x=long, y=lat, group =group)) + geom_polygon(colour="grey40", fill="grey40")
for (name in unique(loc_pie[['Region']])) {
loc_region <- filter(loc_pie, Region %in% name)
pie_tmp <- ggplot(data = loc_region, aes(x = factor(1), y = div, fill = Group3)) +
geom_bar(width = 1, stat = "identity") + coord_polar(theta = "y") +
scale_fill_discrete(drop = FALSE) +
xlab(NULL) + ylab(NULL) + theme_tree() +
theme_transparent()
lat_region <- loc_region[[1,'lat']]
long_region <- loc_region[[1,'long']]
p %<>% subview(pie_tmp, long_region, lat_region, width = .07, height = .07)
}
p
Высота ширины ширины была выбрана вручную, они соответствуют доле subview по отношению к полной.
Для полноты, loc_pie
можно получить:
