Does a multi-value purrr::pluck exist?

Question

Seems like a basic question and perhaps I\'m just missing something obvious ... but is there any way to pluck a sublist (with purrr)? More specifically

Answer 1

Here's my take on it. Not based on purrr thus slightly off topic, but compatible with the tidyverse's general interface principle of playing nicely with pipes.

pluck_multiple <- function(x, ...) {
  `[`(x, ...)
}

x <- list(a = 1, b = 2, c = list(x = TRUE, y = FALSE))

pluck_multiple(x, c("a", "b"))
#> $a
#> [1] 1
#> 
#> $b
#> [1] 2
pluck_multiple(x, 2:3)
#> $b
#> [1] 2
#> 
#> $c
#> $c$x
#> [1] TRUE
#> 
#> $c$y
#> [1] FALSE
