In redist: Simulation Methods for Legislative Redistricting

Calculate Group Proportion by District

Description

redist.group.percent computes the proportion that a group makes up in each district across a matrix of maps.

Usage

group_frac(
  map,
  group_pop,
  total_pop = map[[attr(map, "pop_col")]],
  .data = cur_plans()
)

redist.group.percent(plans, group_pop, total_pop, ncores = 1)

Arguments

map	a redist_map object
group_pop	A numeric vector with the population of the group for every precinct.
total_pop	A numeric vector with the population for every precinct.
.data	a redist_plans object
plans	A matrix with one row for each precinct and one column for each map. Required.
ncores	Number of cores to use for parallel computing. Default is 1.

Value

matrix with percent for each district

Examples

data(fl25)
data(fl25_enum)

cd <- fl25_enum$plans[, fl25_enum$pop_dev <= 0.05]

redist.group.percent(plans = cd,
    group_pop = fl25$BlackPop,
    total_pop = fl25$TotPop)
