In choisy/vietnam63: Shape files of Vietnam after 2008.

vietnam63

This package contains the polygons of the communes (11,163), districts (703) and provinces (63) or Vietnam after the last major administrative border update of 2008, January 1st (essentially the merging of the provinces of Ha Tay and Ha Noi). The package contains 6 SpatialPolygonsDataFrame: communes, districts, and provinces for low polygons resolution and communes_r, districts_r, and provinces_r for high polygons resolution. These objects can be loaded with the base R data function:

library(vietnam63)
data(communes)
data(districts)
data(provinces)

And can be plotted with the sp plot method:

library(sp)
plot(communes)
plot(districts)
plot(provinces)

The attributes of these spatial objects are:

head(communes@data)
head(districts@data)
head(provinces@data)

And we can verify the consistency between the 3 spatial objects:

length(communes_r)
length(unique(communes_r$district_id))
length(districts_r)
setdiff(communes_r$district_id, districts_r$district_id)
length(unique(districts_r$province_id))
length(provinces_r)
setdiff(provinces_r$province_id, districts_r$province_id)
