spt_wt: Create time lagged spatial weights

In sfdep: Spatial Dependence for Simple Features

Create time lagged spatial weights

Description

Given a space-time-lagged neighbor list and a weights lists, e.g. made by st_dist_band() or st_contiguity(), create a corresponding weights list.

Usage

spt_wt(wt, nbt, n_times, n_locs, k)

Arguments

wt	a weights lists created from a spacetime object's geometry context.
nbt	a time-lagged spatial neighbors list created by spt_nb()
n_times	the number of time slices
n_locs	the number of locations

Details

It is intended that spt_wt() is used following the use of spt_nb() using the same input arguments. This ensures that the time-lagged spatial weights are correctly associated with the time-lagged spatial neighbors.

Value

a weight list with same cardinality as nbt
