enframe

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.

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

deframe(x)

`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.

x = 1:3
enframe(x)

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