Chapter 7 Geometry manipulation
To manipulate geometries, there are few options. For spatial objects defined
with sp, there is a specific package to manipulate vector objects: rgeos.
The equivalent of most common functions in sp are found in sf.
Finally, there are a set of interesting functions in raster to handle
the manipulation of rasters with vector objects.
Let’s first load the packages required and download a simple shapefile of Belgium.
library(sp)
library(sf)
library(rgeos)
library(raster)
bel2 <- getData(name = "GADM", country = "BEL", path = "data", level = 2)#R> Warning in getData(name = "GADM", country = "BEL", path = "data", level = 2): getData will be removed in a future version of raster
#R> . Please use the geodata package instead
