问题描述
我在下面的 Excel 中导入了数据以在 R 中创建气泡图:
# A tibble: 6 x 3
Country Series `2019`
<chr> <chr> <dbl>
1 United Kingdom GDP per capita 42354.
2 United Kingdom Life Expectancy 81
3 United Kingdom Population (M) 67
4 United States GDP per capita 65298.
5 United States Life Expectancy 78.8
6 United States Population (M) 328
我写了一个代码,但它没有绘制任何内容。如何制作气泡图?
bubble2 <- mutate_all(bubble,function(x) as.numeric(as.character(x))) %>%
pivot_longer(cols=-c("Country","Series"),names_to="year") %>%
mutate(Year=as.numeric(year)) %>%
select(-year) %>%
ggplot(aes(x="GDP per capita",y="Life Expectancy",size="Population (M)",fill=Country)) +
geom_point(alpha=0.5,shape=21,color="black") +
scale_size(range = c(10,1400),name="Population (M)") +
scale_fill_viridis(discrete=TRUE,guide=FALSE,option="A") +
ylab("Life Expectancy") +
xlab("Gdp per capita")
编辑 我又添加了 10 个国家并调整了代码:
bubble2 <- bubble %>%
pivot_wider(names_from = "Series",values_from = `2019`)
ggplot(bubble2,aes(x = `GDP per capita`,y = `Life Expectancy`,size = `Population (M)`,fill = Country)) +
geom_point(alpha = 0.5,shape = 21,color = "black") +
geom_text(aes(label = Country),size = 8 / .pt) +
#ggrepel::geom_text_repel(aes(label = Country),size = 8 / .pt) +
scale_size(range = c(.1,24),name="Population (M)") +
ylab("Life Expectancy") +
xlab("Gdp per capita") +
theme(axis.title = element_text(size=8),plot.title = element_text(hjust = 0.5))
但是关于人口的传说改变了。如何显示正确的人口图例并取出国家图例?
