使用r比较两个数据帧

library(dplyr)

df1 <- data.frame(ID = c(1, 2, 3),
                  Name = c("John", "Jane", "Tom"),
                  Age = c(25, 30, 35))

df2 <- data.frame(ID = c(1, 2, 4),
                  Name = c("John", "Jane", "Mike"),
                  Age = c(25, 30, 40))

diff_df <- setdiff(df1, df2)

common_df <- intersect(df1, df2)

diff_df <- anti_join(df1, df2)

merged_df <- full_join(df1, df2, by = c("ID", "Name", "Age"))
