How to use ensym as a variable to store values within function

Question

How can I use ensym or another appropriate function that will store this as a variable and assign a value to it.

For example:

quest <- 'a'
list(rlang::ensym(quest) = 1)
>Error: unexpected '=' in "list(rlang::ensym(quest)="

Expected output:

$a
[1] 1

Answer 1

fully rlang approach might be

library(rlang)
quest <- 'a'
list2(!!(quest) := 1)

Answer 2

With tidyverse, we can use dplyr::lst

dplyr::lst(!! quest := 1)
$a
[1] 1

---

Or in base R, use setNames

setNames(list(1), quest)
$a
[1] 1

Answer 3

Here is an alternative way:

1. Create an empty list lst.
2. Use [[ to add a new element to the list with the name specified by quest variable and assign the value 1 to it:

quest <- 'a'
lst <- list()
lst[[quest]] <- 1
lst

$a
[1] 1
