Transforms a distance matrix into a matrix of weights — weights_from_distance_matrix • spatialRF

Transforms a distance matrix into weights (1/distance.matrix) normalized by the row sums. Used to compute Moran's I values and Moran's Eigenvector Maps. Allows to apply a threshold to the distance matrix before computing the weights.

weights_from_distance_matrix(
  distance.matrix = NULL,
  distance.threshold = 0
)

distance.matrix

Distance matrix. Default: NULL.

distance.threshold

Numeric, positive, in the range of values of distance.matrix. Distances below this value in the distance matrix are set to 0., Default: 0.

A weighted distance matrix.
