多变量散点图

Question

Scatterplot reference

data set

谁能帮我画出第一张图中的三个散点图？理想情况下使用 plot() 函数。

Answer 1

require(tidyverse)
require(ggplot2) 

df <- tibble(
  image = 1:18,
  m_r_exsal = rnorm(18, 5, 2), 
  m_r_sal = rnorm(18, 6, 2), 
  female = c(rep(1, 18/2), rep(0, 18/2)), 
  lg_salary = rnorm(18, 5, 1.5), 
  deviation = rnorm(18, 1, 1), 
  chinese = c(rep(1, 6), rep(0, 18/3*2)), 
  european = c(rep(0, 6), rep(1, 6), rep(0, 6)), 
  american = c(rep(0, 18/3*2), rep(1, 6))
)

示例数据：

# A tibble: 18 x 9
   image m_r_exsal m_r_sal female lg_salary deviation chinese european american

制作情节：

df %>%  
  mutate(chinese = case_when(chinese == 1 ~ "chinese"), 
         european = case_when(european == 1 ~ "european"), 
         american = case_when(american == 1 ~ "american"), 
         female = case_when(female == 1 ~ "female", 
                            TRUE ~ "male")) %>%  
  unite(country, chinese:american, remove = TRUE, sep = "") %>%  
  mutate(country = country %>% str_remove_all("NA")) %>%  
  ggplot() + 
  aes(lg_salary, deviation, col = female) + 
  geom_point() + 
  geom_smooth(method = "lm", se = FALSE) + 
  facet_wrap(~ country)
