redist.plot.wted.adj: Plot Weighted Border Adjacency

In redist: Simulation Methods for Legislative Redistricting

Plot Weighted Border Adjacency

Description

Plots the weighted adjacency graph by how often precincts coocur. If an argument to counties is provided, it subsets the edges to plot to those that cross over the county boundary.

Usage

redist.plot.wted.adj(
  shp,
  plans,
  counties = NULL,
  ref = TRUE,
  adj = NULL,
  plot_shp = TRUE
)

Arguments

shp	A SpatialPolygonsDataFrame, sf object, or redist_map. Required.
plans	A redist_plans object or matrix of redistricting plans, where each column indicates a plan and each
counties	unquoted name of a column in shp or a vector of county assignments. Subsets to edges which cross this boundary if supplied.
ref	Plot reference map? Defaults to TRUE which gets the existing plan from
adj	A zero-indexed adjacency list. Extracted from shp if shp is a redist_map. Otherwise created with redist.adjacency if not supplied. Default is NULL.
plot_shp	Should the shapes be plotted? Default is TRUE.

Value

ggplot

Examples

data(iowa)
shp <- redist_map(iowa, existing_plan = cd_2010, pop_tol = 0.01)
plans <- redist_smc(shp, 100)
redist.plot.wted.adj(shp, plans = plans, counties = region)
