wt |
a weights list—i.e. as created by |
Returns a n x n matrix
# make a grid g <- sf::st_make_grid( cellsize = c(10, 10), offset = c(0, 0), n = c(2, 2) ) # create neighbors nb <- st_contiguity(g) # cast to matrix nb_as_matrix(nb) # create weights wt <- st_weights(nb) # cast as matrix wt_as_matrix(nb, wt)
