Description

Calculates the spatial lag of a numeric variable given a neighbor and weights list.

Usage

st_lag(x, nb, wt, na_ok = FALSE, allow_zero = NULL, ...)

Value

a numeric vector with same length as x

Arguments

x

A numeric vector

nb

A neighbor list object as created by st_neighbors().

wt

A weights list as created by st_weights().

na_ok

allow_zero
