Convert a Named Vector into a data.table and Vice Versa

enframe() returns a data.table::data.table() with two columns: The names of x (or seq_along(x) if unnamed) and the values of x.

deframe() converts a two-column data.frame to a named vector. If the data.frame only has a single column, an unnamed vector is returned.

Usage

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

deframe(x)

Arguments

x: (vector() (enframe()) or data.frame() (deframe()))
Vector to convert to a data.table::data.table().
name: (character(1))
Name for the first column with names.
value: (character(1))
Name for the second column with values.

Value

data.table::data.table() or named vector.

Examples

x = 1:3
enframe(x)
#>     name value
#>    <int> <int>
#> 1:     1     1
#> 2:     2     2
#> 3:     3     3

x = set_names(1:3, letters[1:3])
enframe(x, value = "x_values")
#>      name x_values
#>    <char>    <int>
#> 1:      a        1
#> 2:      b        2
#> 3:      c        3
