(For internally use and test only) Queen Contiguity Spatial Weights

Description

Create a Queen contiguity weights with options of "order", "include lower order" and "precision threshold"

Usage

gda_queen_weights(
  geoda_obj,
  order = 1,
  include_lower_order = FALSE,
  precision_threshold = 0
)

Arguments

geoda_obj	An object of [geoda] class
order	(Optional) Order of contiguity
include_lower_order	(Optional) Whether or not the lower order neighbors should be included in the weights structure
precision_threshold	(Optional) The precision of the underlying shape file is insufficient to allow for an exact match of coordinates to determine which polygons are neighbors

Value

An instance of Weight-class
