In ropenscilabs/eechidna: Exploring Election and Census Highly Informative Data Nationally for Australia

aec_add_carto_f - computes and binds the cartogram coordinates to original data

Description

Add the cartogram locations as new variables to original data and make any of these that were not made equal to the original centroids. This is simply all of the Australian electoral cartogram steps in one hit.

Usage

aec_add_carto_f(nat_data)

Arguments

nat_data

subset of data with centroids of electoral divisions

Examples

library(eechidna)
library(dplyr)
library(ggplot2)

nat_map16 <- nat_map_download(2016)
nat_data16 <- nat_data_download(2016)

nat_data16 <- nat_data16 %>% select(-c(x,y)) # remove existing cartogram coordinates
nat_data_cart <- aec_add_carto_f(nat_data16)
# Map theme
library(ggthemes)

ggplot(data=nat_data_cart, aes(map_id=id)) +
  geom_map(map = nat_map16, fill="grey90", colour="white") +
    geom_point(aes(x=x, y=y), size=2, alpha=0.4,
                 colour="#572d2c", inherit.aes=FALSE) +
    expand_limits(x=nat_map16$long, y=nat_map16$lat) +
    theme_map() + coord_equal()
