合并r中具有相同行名称的2个数据帧

我有2个数据帧，我想将它们合并成一个数据帧，每个数据帧对应于彼此的行名称值。如果您能告诉我如何在绘图（ggplot2或绘图）上绘制它们，我将不胜感激

df1：

df2：

使用

merge

，我们可以使用

by

作为

行。名称

out <- merge(df1, df2, by = 'row.names')

或使用

tidyverse

library(ggplot2)
library(dplyr)
library(tidyr)
merge(df1, df2, by = 'row.names') %>% 
   rename(nm = 'Row.names') %>%  # // rename the column name
   type.convert(as.is = TRUE) %>%  # // some columns were not of the correct type
   pivot_longer(cols = -nm) %>% # // reshape to 'long' format
   ggplot(aes(x = name, y = value, fill = nm)) + # // plot as bar
        geom_col() + 
        theme_bw()

-输出

我在考虑更多的散点图，但感谢合并部分。

out <- merge(df1, df2, by = 'row.names')

barplot(`row.names<-`(as.matrix(out[-1]),
          out$Row.names), col = c('blue', 'green', 'red'), legend = TRUE)

library(ggplot2)
library(dplyr)
library(tidyr)
merge(df1, df2, by = 'row.names') %>% 
   rename(nm = 'Row.names') %>%  # // rename the column name
   type.convert(as.is = TRUE) %>%  # // some columns were not of the correct type
   pivot_longer(cols = -nm) %>% # // reshape to 'long' format
   ggplot(aes(x = name, y = value, fill = nm)) + # // plot as bar
        geom_col() + 
        theme_bw()
