Get minimum threshold of distance that makes sure each observation has at least one neighbor

min_distthreshold(sf_obj, is_arc = FALSE, is_mile = TRUE)

Arguments

sf_obj

An sf (simple feature) object

is_arc

(optional) FALSE (default) or TRUE, compute arc distance between two observations

is_mile

(optional) TRUE (default) or FALSE, if 'is_arc' option is TRUE, then 'is_mile' will set distance unit to 'mile' or 'km'.

Value

A numeric value of minimum threshold of distance

Examples

if (FALSE) { # \dontrun{
library(sf)
guerry_path <- system.file("extdata", "Guerry.shp", package = "rgeoda")
guerry <- st_read(guerry_path)
dist_thres <- min_distthreshold(guerry)
dist_thres
} # }
