Sample list:



sublist <- list(foo = "foo", bar = "bar", baz = "baz")

sample_list <- list(a = sublist,
 b = sublist,
 c = sublist)


Here, I would like to create a sublist for the elements in a b and c within each of the aforementioned lists. I.e I would like to nest foo, bar, baz, one list further down, after I have created the list in the manner above.



Desired output:



sample_list <- list(a = list(a_down = sublist),
 b = list(b_down = sublist),
 c = list(c_down = sublist))

    Something like lapply(1:3, function(i) setNames(list(sublist), letters[i]))?

We can use imap



library(purrr)
out2 <- imap(sample_list, ~ set_names(list(.x), paste0(.y, "_down")))


or making use of lst



imap(sample_list, ~ lst(!! paste0(.y, "_down") := .x))


-checking with OP's output



identical(out, out2)
#[1] TRUE
