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)

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.

Value

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

Examples

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

# Or many plans:

# slower, beware!
comp_box_reock(plans = nh_m[, 3:5], shp = nh)
