redist.enumpart: Enumerate All Parititions (Fifield et al. 2020)

Description

Single function for standard enumeration analysis, using ZDD methodology (Fifield, Imai, Kawahara, and Kenny 2020).

Usage

redist.enumpart(
  adj,
  unordered_path,
  ordered_path,
  out_path,
  ndists = 2,
  all = TRUE,
  n = NULL,
  weight_path = NULL,
  lower = NULL,
  upper = NULL,
  init = FALSE,
  read = TRUE,
  total_pop = NULL
)

Value

List with entries district_membership and parity.

Arguments

adj

zero indexed adjacency list.

unordered_path

valid path to output the unordered adjacency map to

ordered_path

valid path to output the ordered adjacency map to

out_path

Valid path to output the enumerated districts

ndists

number of districts to enumerate

all

boolean. TRUE outputs all districts. FALSE samples n districts.

n

integer. Number of districts to output if all is FALSE. Returns districts selected from uniform random distribution.

weight_path

A path (not including ".dat") to a space-delimited file containing a vector of vertex weights, to be used along with lower and upper.

lower

A lower bound on each partition's total weight, implemented by rejection sampling.

upper

An upper bound on each partition's total weight.

init

Runs redist.init.enumpart. Defaults to false. Should be run on first use.

read

boolean. Defaults to TRUE. reads

total_pop

the vector of precinct populations
