distance_weights: Create a distance-based weights

In lixun910/rgeoda: R Library for Spatial Data Analysis

Description

Create a distance-based weights

Usage

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

Arguments

geoda_obj	An instance of geoda
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.

Value

w An instance of GeoDaWeight

Examples

guerry_path <- system.file("extdata", "Guerry.shp", package = "rgeoda")
guerry <- geoda_open(guerry_path)
dist_thres <- min_distthreshold(guerry)
dist_w <- distance_weights(guerry, dist_thres)
summary(dist_w)
