extentToVect {enmSdmX}

Convert extent to a spatial polygon

Description

This function returns a SpatVector or sf polygon representing an extent. The input can be a SpatExtent or sf object, or an object from which a SpatExtent (extent) can be obtained.

Usage

extentToVect(x, ...)

Arguments

x

A sf, SpatVector, SpatRaster, sf, or a vector of four numeric values representing (in this order): x-coordinate of western side of the extent, x-coordinate of eastern side, y-coordinate of the southern side, and y-coordinate of the northern side. If numeric coordinates are supplied, the output will not have a CRS assigned to it unless supplied in ...

...

Arguments to supply to vect.

Value

A SpatVector (usual) or, if the input is an sf object, an sf polygon object.

Examples

data(mad0)
madExtent <- extentToVect(mad0)
plot(madExtent, border='blue', lty='dotted')
plot(mad0[1], add=TRUE)

# NB This is the same as:
library(terra)
madExtent <- ext(mad0)
madExtent <- as.polygons(madExtent, crs = crs(mad0))
