如何循环遍历 2 个数据帧或（列表）并将每个值替换为 R 中的 label

Question

My first variable called data

index <- seq(1:15)
name <- c('USA', "UK", "Canada", "Mexico", "Japan", "Brazil", "France", "Portugal", "Spain",
      "Argentina", "Qatar", "Dubai", "Malaysia", "Indonésia", "Signapour")
data <- cbind(index, name)

My second variable called df:

 var_1 <- 5 ;var_2 <- 3 ;var_3 <- 2 ;var_4 <- 9
 var_5 <- 1 ; var_6 <- 6 ; var_7 <- 7 ; var_8 <- 8 ; var_9 <- 4
 var_10 <- 15 ; var_11 <- 14 ; var_12 <- 12 ; var_13 <- 13
var_14 <- 11 ; var_15 <- 10

df <- cbind.data.frame(var_1, var_2, var_3, var_4, var_5, var_6, var_7, var_8, var_9, var_10, 
 var_11, var_12, var_13, var_14, var_15)

df 

I want to create a loop using for() and if(), to replace every value in df for each variable with column "name" in data

Does this do what you want?

data = as.data.frame(unlist(data))
df[1,]= data$name
