Make a traceplot for a summary statistic — redist.plot.trace • redist

For a statistic in a redist_plans object, make a traceplot showing the evolution of the statistic over MCMC iterations.

redist.plot.trace(plans, qty, district = 1L, ...)

Arguments

plans: the redist_plans object.
qty: <data-masking> the statistic.
district: for redist_plans objects with multiple districts, which district to subset to for plotting. Set to NULL to perform no subsetting.
...: passed on to geom_line

Value

A ggplot

Examples

library(dplyr)
data(iowa)

iowa_map <- redist_map(iowa, existing_plan = cd_2010, pop_tol = 0.05)
plans <- redist_mergesplit_parallel(iowa_map, nsims = 200, chains = 2, silent = TRUE) %>%
    mutate(dem = group_frac(iowa_map, dem_08, dem_08 + rep_08)) %>%
    number_by(dem)
redist.plot.trace(plans, dem, district = 1)
