(For internally use and test only) Distance-based Spatial Weights

Create a distance-based weights

gda_distance_weights( geoda_obj, dist_thres, power = 1, is_inverse = FALSE, is_arc = FALSE, is_mile = TRUE )

Arguments

  • geoda_obj: An instance of geoda-class
  • dist_thres: A positive numeric value of distance threshold
  • power: (optional) The power (or exponent) of a number indicates how many times to use the number in a multiplication.
  • is_inverse: (optional) FALSE (default) or TRUE, apply inverse on distance value
  • is_arc: (optional) FALSE (default) or TRUE, compute arc distance between two observations
  • is_mile: (optional) TRUE (default) or FALSE, convert distance unit from mile to km.

Returns

An instance of Weight-class

Examples

## Not run: guerry_path <- system.file("extdata", "Guerry.shp", package = "rgeoda") guerry <- geoda_open(guerry_path) dist_thres <- gda_min_distthreshold(guerry) dist_w <- gda_distance_weights(guerry, dist_thres) summary(dist_w) ## End(Not run)
