如何在r中命名列表的元素？

假设我有以下列表：

my_variable <- list()
x <- c(1,2,3,4)
y <- c(4,5,7,3)
for ( i in 1:4){
my_variable[[i]] <- x[i]*y[i]+2
}

如何命名输出的元素，如下所示：

 > my_variable
    First_result
[1] 6

    Second_result
[1] 12

---

依此类推。

您可以使用

paste0

和

names

# So first you define vector of names:
names1 <- c("First","Second","Third","Fourth")
# And second you paste them to your list
names(my_variable) <- paste0(names1,"_result",  sep = "")

#And the output
$First_result
[1]  6 12 23 14

$Second_result
[1]  6 12 23 14

$Third_result
[1]  6 12 23 14

$Fourth_result
[1]  6 12 23 14

#首先定义名称向量：
名称1
名称（我的变量）您可以使用
名称（我的变量）
# So first you define vector of names:
names1 <- c("First","Second","Third","Fourth")
# And second you paste them to your list
names(my_variable) <- paste0(names1,"_result",  sep = "")

#And the output
$First_result
[1]  6 12 23 14

$Second_result
[1]  6 12 23 14

$Third_result
[1]  6 12 23 14

$Fourth_result
[1]  6 12 23 14
