通过gganimate能够达到非常酷炫的动态效果

1.必要的库文件

library(gganimate)
library(ggplot2)
library(dplyr)
library(gapminder)
library(ggthemes)
library(gifski)
library(readr)
library(tidyr)

2.导入数据

str(gapminder)

3.生成静态图片

graph1 = gapminder %>%
  ggplot(aes(x=gdpPercap, y=lifeExp, color=continent, size=pop)) +
  geom_point(alpha = 0.7, stroke = 0) +
  theme_fivethirtyeight() +
  scale_size(range=c(2,12), guide="none") +
  scale_x_log10() +
  labs(title = "Life Expectancy vs GDP",
       x = "Income",
       y = "Life Expectancy",
       color = "Continent",
       caption = "Source: Gapminder") +
  theme(axis.title = element_text(),
        text = element_text(family = "Rubik"),
        legend.text=element_text(size=10)) +
  scale_color_brewer(palette = "Set2")

效果如下

4.增加动画

graph1.animation = graph1 +
  transition_time(year) +
  labs(subtitle = "Year: {frame_time}") +
  shadow_wake(wake_length = 0.1)
animate(graph1.animation, height = 500, width = 800, fps = 30, duration = 10,
        end_pause = 60, res = 100)
anim_save("gapminder graph.gif")

效果图
