Description

convert a spatial nb object to a matching STF object

Usage

nbMult(nb, st, addT = TRUE, addST = FALSE)

Arguments

nb

object of class nb (see package spdep), which is valid for the spatial slot of object st: length(nb) should equal length(st@sp)

st

object of class STF

addT

logical; should temporal neighbours be added?

addST

logical; should spatio-temporal neighbours be added?

Value

object of class nb

Details

if both addT and addST are false, only spatial neighbours are added for each time replicate.
