Description

Erase parts of a SpatVector with another SpatVector (or SpatExtent). The inverse of this can be done with intersect and crop.

Usage

## S4 method for signature 'SpatVector,SpatVector'
erase(x, y)

## S4 method for signature 'SpatVector,SpatExtent'
erase(x, y)

Arguments

`x`	SpatVector
`y`	SpatVector or SpatExtent

Value

SpatVector or SpatExtent

Examples

f <- system.file("ex/lux.shp", package="terra")
v <- vect(f)
e <- ext(5.6, 6, 49.55, 49.7)
x <- erase(v, e)

p <- vect("POLYGON ((5.8 49.8, 6 49.9, 6.15 49.8, 6 49.6, 5.8 49.8))")
y <- erase(v, p)
