redist (version 4.2.0)

plot.redist_constr: Visualize constraints

Description

Plots the constraint strength versus some running variable. Currently supports visualizing the grp_hinge, grp_inv_hinge, and grp_pow constraints.

Usage

# S3 method for redist_constr
plot(x, y, type = "group", xlim = c(0, 1), ...)

Value

A ggplot object

Arguments

x

A redist_constr object.

y

Ignored.

type

What type of constraint to visualize. Currently supports only "group", for visualizing constraint strength by group share.

xlim

Range of group shares to visualize.

...

additional arguments (ignored)

Examples

data(iowa)
iowa_map <- redist_map(iowa, existing_plan = cd_2010, pop_tol = 0.05)
constr <- redist_constr(iowa_map)
constr <- add_constr_grp_hinge(constr, strength = 30,
                               dem_08, tot_08, tgts_group = 0.5)
constr <- add_constr_grp_hinge(constr, strength = -20,
                               dem_08, tot_08, tgts_group = 0.3)
plot(constr)
