Examples

# load and format reference data
stl <- stLouis
stl <- dplyr::mutate(stl, TRACTCE = as.numeric(TRACTCE))

# create cluster
cluster <- qm_define(118600, 119101, 119300)

# create simple cluster object
cluster_obj <- qm_create(ref = stl, key = TRACTCE, value = cluster,
    rid = 1, cid = 1, category = "positive")

# test cluster object
qm_is_cluster(cluster_obj)
qm_is_cluster(cluster_obj, verbose = TRUE)
