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.

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

deframe(x)

Arguments

x	An atomic 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

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

Examples

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