wmat: Spatial weights matrix

In andybega/wstates: Spatial Lagging for Country-Year Data

Description

Spatial weights matrix class / constructor

Usage

wmat(w, geom, type = NULL, coords = NULL)

Arguments

w	a matrix
geom	geometry from which the matrix was constructed. Used for plotting.
type	String describing the weights matrix type
coords	Alternative coordinates to use when plotting, otherwise will default to centroids.

Examples

library("sf")

data("est_adm1")
w <- w_contiguity(sf::st_geometry(est_adm1))
w
plot(w)

# the vertices default to centroid coordinates; this can be changed by
# setting alternative coordinates
coords <- st_as_sf(as.data.frame(est_adm1), coords = c("caplong", "caplat"),
                   remove = TRUE, crs = 4326)
coords <- st_geometry(coords)
w <- set_coords(w, coords)
plot(w)
