I have two lists that I want two keep in list format.

list1 <- list("two", "one", "three")
list2 <- list(2, 1, 3)

I want to use list2 to reorder list1 while keeping both in list format. I would like the output of both lists to be as follows.

> list1
#[[1]]
#[1] "one"
#
#[[2]]
#[1] "two"
#
#[[3]]
#[1] "three"

> list2
#[[1]]
#[1] 1
#
#[[2]]
#[1] 2
#
#[[3]]
#[1] 3

How can I do this?

CodePudding user response：

You can use order for this purpose; however, order expects a vector, so having list2 be a list is a bit inconvenient:

result = list1[order(unlist(list2))]
