如何获取包含区域和子区域的地图 [英] How to obtain maps with regions and subregions

问题描述

我的问题:我想从给定国家/地区获得地图，其中r包含分区.

到目前为止:例如， map 软件包提供了 counties 地图，该数据库可生成根据美国人口普查数据生成的美国大陆各县的地图.例如，提供子区域的 italy 地图(例如一对代码行)可以绘制该区域:

  it<-ggplot2 :: map_data("italy")库(ggplot2)ggplot(it，aes(long，lat，group = group))+geom_polygon()+coord_fixed() 

我想在其他国家/地区获得相同的地图，但是不幸的是，我认为 maps 包仅提供美国，意大利和法国的此信息.是否有提供此类信息的包装?

解决方案

基于@alistaire的评论:

  library("rnaturalearth")库("ggplot2")西班牙<-ne_states(国家=西班牙"，returnclass ="sf")ggplot(数据=西班牙)+geom_sf()

My problem: I want to obtain a map from a given country with subregions in r.

So far: For example map package provides counties map which database produces a map of the counties of the United States mainland generated from US Department of the Census data. Or for example italy map which provides subregions, such as in a pair of lines of code is possible to plot it:

it <- ggplot2::map_data("italy")

library(ggplot2)

ggplot(it, aes(long, lat, group = group)) +
  geom_polygon() +
  coord_fixed()

I would like to obtain same maps for another countries but unfortunately I think that maps package only provides this information for USA, Italy and France. Is there a package which provides such information?

解决方案

Based on the @alistaire's comment:

library("rnaturalearth")
library("ggplot2")
spain <- ne_states(country = "spain", returnclass = "sf")

ggplot(data = spain) +
  geom_sf()

As proposed here regions can be obtained just using group_by and summarise:

spain %>% 
  group_by(region) %>% 
  summarise() %>% 
  ggplot() +
  geom_sf() +
  theme(legend.position = 'none')
