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

Description

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)

Value

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

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.

Examples

x = 1:3
enframe(x)

x = set_names(1:3, letters[1:3])
enframe(x, value = "x_values")
