R 中的分组条形图 - 'height' 必须是向量或矩阵

Question

我有以下数据，我想制作一个分组条形图，其中显示按位置分组的 total_deaths_per_million 和 total_tests_per_thousand

 location total_deaths_per_million total_tests_per_thousand
  <chr>                       <dbl>                    <dbl>
1 Albania                      617.                     150.
2 Denmark                      407.                    2818.
3 Germany                      837.                     524.
4 Russia                       578.                     756.

每次我使用 barplot 时它都会说“'height' 必须是向量或矩阵”

Answer 1

  library(tidyverse)
  df <- tribble(~location, ~total_deaths_per_million, ~total_tests_per_thousand,
 "Albania" ,                     617,                     150,
 "Denmark" ,                     407,                    2818,
 "Germany" ,                     837,                     524,
 "Russia"  ,                     578,                     756)

df2 <- df %>% 
  pivot_longer(-location)
barplot(value ~ name + location, data = df2,
        beside = TRUE)

df %>% 
  pivot_longer(-location) %>% 
  ggplot(aes(location, value, fill = name)) +
  geom_col(position = "dodge")

df %>% 
  pivot_longer(-location) %>% 
  ggplot(aes(name, value)) +
  geom_col(position = "dodge") +
  facet_wrap(~location) + coord_flip()

R 中的分组条形图 - 'height' 必须是向量或矩阵

Grouped bar plot in R - 'height' must be a vector or a matrix
