unspecified

A 1d vector of unspecified type

This is a partial type used to represent logical vectors that only contain NA. These require special handling because we want to allow NA to specify missingness without requiring a type.

Usage

unspecified(n = 0)
vec_unspecified_cast(x, to)
# S3 method for vctrs_unspecified
vec_type2(x, y)

Details

vec_unspecified_cast() is a helper to use in your vec_cast() methods. See vignette("s3-vector") for detail.
