Create vectors matching a given length

These functions construct vectors of a given length, with attributes specified via dots. Except for new_list() and new_raw(), the empty vectors are filled with typed missing values. This is in contrast to the base function base::vector() which creates zero-filled vectors.

Usage

new_logical(n, names = NULL)

new_integer(n, names = NULL)

new_double(n, names = NULL)

new_character(n, names = NULL)

new_complex(n, names = NULL)

new_raw(n, names = NULL)

new_list(n, names = NULL)

Arguments

n

The vector length.

names

Names for the new vector.

Lifecycle

These functions are likely to be replaced by a vctrs equivalent in the future. They are in the questioning lifecycle stage.
