如何將多個.shp
文件作爲一個對象讀取?將多個`.shp`文件作爲一個對象讀取?
我想簡單地閱讀代碼。
nc <- st_read(dsn = "nc",
layer = c("nc1","nc2"))
將多個文件作爲對象讀取的最佳方法是什麼?
library(sf)
nc <- st_read(system.file("shape/nc.shp", package="sf"))
nc1 <- nc[1:50, ]
nc2 <- nc[51:100, ]
st_write(nc1,
dsn = "nc",
layer = "nc1",
driver = "ESRI Shapefile")
st_write(nc2,
dsn = "nc",
layer = "nc2",
driver = "ESRI Shapefile",update = T)
如果你在閱讀他們的空間的多邊形data.frame,你可以將它們合併的建議[這裏](https://gis.stackexchange.com/questions/155328/merging-multiple- spatialpolygondataframes-into-1-spdf-in-r),如果沒有,你可能需要尋找arcpy解決方案。 –
