comp_box_reock: Calculate Box Reock Compactness

Description

Box reock is the ratio of the area of the district by the area of the minimum bounding box (of any rotation). Scores are bounded between 0 and 1, where 1 is most compact.

Usage

comp_box_reock(plans, shp, epsg = 3857, ncores = 1)

Value

A numeric vector. Can be shaped into a district-by-plan matrix.

Arguments

plans

A redist_plans object or plans_matrix where each row indicates a district assignment and each column is a plan.

shp

A redist_map object, tibble, or data frame with an sf geometry column.

epsg

Numeric EPSG code to use to project the shapefile, if needed. Default is 3857.

ncores

Integer number of cores to use. Default is 1.

Examples

#' data(nh)
data(nh_m)
# For a single plan:
comp_box_reock(plans = nh$r_2020, shp = nh)

# Or many plans:
# \donttest{
# slower, beware!
comp_box_reock(plans = nh_m[, 3:5], shp = nh)
# }
