Source: R/clustering.R

Join count ratio is the join counts, the number of times a category is surrounded by neighbors of the same category, over the total number of neighbors after converting each category to a dummy variable.

join_count_ratio(clusters, w)

Arguments

clusters

A cluster classification variable (categorical values from a dataframe or values returned from cluster functions)

w

An instance of Weight class

Value

A data.frame with names "Cluster", "N", "Neighbors", "Join Count", "Ratio"

Examples

if (FALSE) { # \dontrun{
library(sf)
guerry_path <- system.file("extdata", "Guerry.shp", package = "rgeoda")
guerry <- st_read(guerry_path)
queen_w <- queen_weights(guerry)
data <- guerry[c('Crm_prs','Crm_prp','Litercy','Donatns','Infants','Suicids')]
clusters <- skater(5, queen_w, data)
results <- join_count_ratio(clusters, queen_w)
results
} # }
