In redist: Simulation Methods for Legislative Redistricting

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
)

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

Value

List with entries district_membership and parity.
