r - 根据条件使用另一个值的值更新数据框中的整个列

Question

我有两个数据框，我希望组合唯一值并单独更新现有记录的列值，而不是添加新记录。

DF1<-data.frame(name = c("Test1","Test2","Test3"),
                Value = c(10,20,30),
                Remarks = c("Good","Best","Perfect")
)

DF2<- data.frame(name = c("Test","Test2","Test3","Test4"),
                 Value = c(10,22,30, 40),
                 Remarks = c("Good","Best","Perfect","NEW"))

我已经尝试过

DF3 <- unique(bind_rows(x = DF1, y = DF2))

结果是

   name Value Remarks
1 Test1    10    Good
2 Test2    20    Best
3 Test3    30 Perfect
4  Test    10    Good
5 Test2    22    Best
7 Test4    40     NEW

但我渴望实现

   name Value Remarks
1 Test1    10    Good
2 Test2    **22**    Best
3 Test3    30 Perfect
4  Test    10    Good
5 Test4    40     NEW

对于现有值，我希望更新而不是添加新记录。

Answer 1

我们可以使用rows_upsert

library(dplyr)
rows_upsert(DF1, DF2)

-输出

   name Value Remarks
1 Test1    10    Good
2 Test2    22    Best
3 Test3    30 Perfect
4  Test    10    Good
5 Test4    40     NEW
