Tibbles can have a list column

Extracting parts of a tibble with a list column:

# whole list column:
df |> pull(z) |> str()

## List of 2
##  $ :List of 2
##   ..$ : num 1
##   ..$ : num 2
##  $ :List of 3
##   ..$ : num 3
##   ..$ : num 4
##   ..$ : num 5

df |> pluck("z") |> str()

## List of 2
##  $ :List of 2
##   ..$ : num 1
##   ..$ : num 2
##  $ :List of 3
##   ..$ : num 3
##   ..$ : num 4
##   ..$ : num 5

# elements inside the list column:
df |> pluck("z", 2, 3)

• dplyr::pull() just takes one variable as argument
• purrr::pluck() is designed to also take subsequent nested elements.
