Libraries / packages

This post is just a continuation of the previous post on animated and interactive maps. We will show four examples of maps created using {ggplot2} and {plotly}.

library(tidyverse)
library(gapminder)
library(gganimate)
library(widgetframe)
library(ggthemes)
library(plotly)
library(viridis)

world <- map_data("world") %>%
  filter(region != "Antarctica")

gapminder_codes <- gapminder::country_codes

gapminder <-gapminder::gapminder_unfiltered


gapminder <- gapminder %>%
  inner_join(gapminder_codes, by= "country") %>%
  mutate(code = iso_alpha)

gapminder_data <- gapminder %>%
  inner_join(maps::iso3166 %>%
               select(a3, mapname), by= c(code = "a3")) %>%
  mutate(mapname = str_remove(mapname, "\\(.*"))

Example 4.

mapa_animado_4 <- gapminder_data %>%
 filter(year %in% c(1992, 2007)) %>%
  right_join(world, by= c(mapname = "region")) %>%
  ggplot(aes(long, lat, 
             group= group, 
             fill= lifeExp)) +
  geom_polygon(aes(frame = year),
               color = "white", 
               size = 0.01) +
  theme_void() +
  scale_fill_viridis(option = "B",
                     name= "Years") +
  labs(title="Life Expectancy")  +
  theme(
    plot.title = element_text(size = 12, hjust = 0.5),
    plot.subtitle = element_text(size = 10, hjust = 0.5),
    plot.caption = element_text(size = 8, hjust = 1)) +
  coord_fixed(ratio = 1.3) 



fig_4 <- ggplotly(mapa_animado_4) %>% animation_slider(currentvalue = list(prefix = "Year ", font = list(color="orange")))
