Converting vectors to data frames, and vice versa

enframe() converts named atomic vectors or lists to one- or two-column data frames. For a list, the result will be a nested tibble with a column of type list. For unnamed vectors, the natural sequence is used as name column.

deframe() converts two-column data frames to a named vector or list, using the first column as name and the second column as value. If the input has only one column, an unnamed vector is returned.

Usage

enframe(x, name = "name", value = "value")

deframe(x)

Arguments

x

A vector (for enframe()) or a data frame with one or two columns (for deframe()).

name, value

Names of the columns that store the names and values. If name is NULL, a one-column tibble is returned; value cannot be NULL.

Value

For enframe(), a tibble with two columns (if name is not NULL, the default) or one column (otherwise).

For deframe(), a vector (named or unnamed).

Examples

enframe(1:3)
#> # A tibble: 3 × 2
#>    name value
#>   <int> <int>
#> 1     1     1
#> 2     2     2
#> 3     3     3
enframe(c(a = 5, b = 7))
#> # A tibble: 2 × 2
#>   name  value
#>   <chr> <dbl>
#> 1 a         5
#> 2 b         7
enframe(list(one = 1, two = 2:3, three = 4:6))
#> # A tibble: 3 × 2
#>   name  value    
#>   <chr> <list>   
#> 1 one   <dbl [1]>
#> 2 two   <int [2]>
#> 3 three <int [3]>
deframe(enframe(3:1))
#> 1 2 3 
#> 3 2 1 
deframe(tibble(a = 1:3))
#> [1] 1 2 3
deframe(tibble(a = as.list(1:3)))
#> [[1]]
#> [1] 1
#> 
#> [[2]]
#> [1] 2
#> 
#> [[3]]
#> [1] 3
