In sfdep: Spatial Dependence for Simple Features

Calculate spatial lag

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, ...)

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	Default FALSE. If, TRUE missing values return a lagged NA.
allow_zero	If TRUE, assigns zero as lagged value to zone without neighbors.
...	See ?spdep::lag.listw for more.

Value

a numeric vector with same length as x

nb <- st_contiguity(geo)
wt <- st_weights(nb)
