Convert a Vector or List to a Tibble

enframe() converts a named atomic vector to a two-column tibble: the first column records the name of the elements in the vector, and the second column records the element values in the vector.

library(tibble)
# create a named vectorx <- c(apple = 5, peach = 7, melon = 9) 
# turn named vector to a two-column tibbleenframe(x) 

Output:
# A tibble: 3 × 2
  name  value
  <chr> <dbl>
1 apple     5
2 peach     7
3 melon     9

If the vector is not named, then a natural numeric sequence is used to create the name column.

enframe(c(1, 3, 6, 19))

Output:
# A tibble: 4 × 2
   name value
  <int> <dbl>
1     1     1
2     2     3
3     3     6
4     4    19

Use name = NULL to turn off the name column. This creates a tibble with a single column.

enframe(c(1, 3, 6, 19), name = NULL)

Output:
# A tibble: 4 × 1
  value
  <dbl>
1     1
2     3
3     6
4    19

You can use enframe() to convert a named list to a tibble in a similar way. The result will be a nested tibble with a column of type list. For unnamed vectors, the natural sequence is used as the name column.

# create a named lista <- list(Mike = .1, Tom = 2:3, Jane = c("x", "y", "z")) a

Output:
$Mike
[1] 0.1 $Tom
[1] 2 3 $Jane
[1] "x" "y" "z"

# convert the list to a tibbleenframe(a)

Output:
# A tibble: 3 × 2
  name  value
  <chr> <list>
1 Mike  <dbl [1]>
2 Tom   <int [2]>
3 Jane  <chr [3]>
