Get shared paths of line or polygon geometries. This can for geometries in a single SpatVector, or between two SpatVectors
Usage
# S4 method for class 'SpatVector'
sharedPaths(x, y=NULL)
Arguments
- x
SpatVector of lines or polygons
- y
missing or SpatVector of lines or polygons
Examples
f <- system.file("ex/lux.shp", package="terra")
v <- vect(f)
plot(v, col="light gray")
text(v, halo=TRUE)
x <- sharedPaths(v)
lines(x, col="red", lwd=2)
text(x, col="blue", halo=TRUE, cex=0.8)
head(x)
#> id1 id2
#> 1 1 2
#> 2 1 4
#> 3 1 5
#> 4 2 3
#> 5 2 4
#> 6 2 5
z <- sharedPaths(v[3,], v[12,])
