结合两个邻国的SpatialPolygonsDataFrame [英] Combining SpatialPolygonsDataFrame of two neighbour countries

问题描述

我想合并两个邻国(例如巴基斯坦和印度)的 SpatialPolygonsDataFrame.我的 MWE 如下:

I want to combine the SpatialPolygonsDataFrame of two neighbour countries like Pakistan and India. My MWE is below:

library(raster)
Pakistan.adm1.spdf <- 
  getData(
    "GADM"
    , country = "Pakistan"
    , level = 1
  )

India.adm1.spdf <- 
  getData(
    "GADM"
    , country = "India"
    , level = 1
  )

如何组合这两个 shapefile?

How can I combine these two shapefiles?

推荐答案

从答案到这个问题，使用rbind 和参数 makeUniqueIDs.

From the answer to this question, use rbind and the argument makeUniqueIDs.

adm1.spdf <- rbind(Pakistan.adm1.spdf, India.adm1.spdf, makeUniqueIDs = TRUE)
plot(adm1.spdf)
