geomander (version 2.3.0)

estimate_up: Estimate Up Levels

Description

Non-geographic partner function to geo_estimate_up. Allows users to aggregate up without the costly matching operation if they've already matched.

Usage

estimate_up(value, group)

Value

numeric vector with each value aggregated by group

Arguments

value

numeric vector. Defaults to 1. Typically population values.

group

matches of length(value) that correspond to row indices of value. Often, this input is the output of geo_match.

Examples

library(dplyr)
set.seed(1)
data(checkerboard)
counties <- checkerboard %>%
  group_by(id <= 32) %>%
  summarize(geometry = sf::st_union(geometry)) %>%
  mutate(pop = c(100, 200))
matches <- geo_match(checkerboard, counties)
estimate_up(value = checkerboard$i, group = matches)
