Usage

freeze(freeze_row, plan, .data = cur_map())

redist.freeze(adj, freeze_row, plan = rep(1, length(adj)))

freeze_row	Required, logical vector where TRUE freezes and FALSE lets a precinct stay free or a vector of indices to freeze
plan	A vector of district assignments, which if provided will create separate groups by district. Recommended. In freeze defaults to the existing plan, if one exists.
.data	a redist_map object
adj	Required, zero indexed adjacency list.

Value

integer vector to group by

Examples

library(redist)
library(dplyr)
data(fl25)
data(fl25_enum)
data(fl25_adj)
plan <- fl25_enum$plans[, 5118]
freeze_id <- redist.freeze(adj = fl25_adj, freeze_row = (plan == 2),
    plan = plan)

data(iowa)
map <- redist_map(iowa, existing_plan = cd_2010, pop_tol = 0.02)
map <- map %>% merge_by(freeze(cd_2010 == 1, .data = .))
