st_nb_dists {sfdep}

Calculate neighbor distances

Description

From an nb list and point geometry, return a list of distances for each observation's neighbors list.

Usage

st_nb_dists(x, nb, longlat = NULL)

Arguments

x

an object of class sfc.

nb

a neighbor list for example created by st_contiguity()

longlat

TRUE if point coordinates are longitude-latitude decimal degrees, in which case distances are measured in kilometers. See ?spdep::nbdists() for more.

Details

Utilizes spdep::nbdists() for distance calculation.

Value

a list where each element is a numeric vector.

geo <- sf::st_geometry(guerry)
nb <- st_contiguity(geo)
