紧急求助，现有两个数据框

如 df1 <- data.frame(di=c(1,2,3,5,7,9),
name=c("li si","zhangsan","xiaohong","wang liu","chen qi","zhao si"),
value1=c(20,21,22,23,24,25),
value2=c(30:31,32,33,34,35)
)
  df2 <- data.frame(di=c(1,2,3,4,10),
name=c("li si","zhangsan","xiaohong","yangjiu", "anyii"),
value1=c(20,21,22,34,36),
value2=c(30,31,32,68,69))

紧急求救，如何得出如df3式的数据框
df3 = (di=c(1,2,3,4,5,7,9,10)
,name=c("li si","zhangsan","xiaohong","yangjiu", "wang liu","chen qi","zhao si","anyii"),
value1=c(40,42,44,23,34,24,25,36),
value2=c(30,31,32,68,33,34,35,69)
)

newdata <- df2[c(4:5),]
total <- rbind(df1, newdata)
total <- total[order(total$di), ]

1. library(dplyr)
   
2. a <- rbind(df1,df2)
   
3. b <- newdata[!duplicated(newdata$name),]
   
4. c <- arrange(new,di)

复制代码

1. xx <- rbind(df1,df2)
   
2. xx[!duplicated(xx),]

复制代码

因为有重复值，简单合并之后，去掉重复的就可以了

偶是初学者，受益匪浅   谢谢楼上两位
