\usage{
vec_seq_along(x)

vec_init_along(x, y = x)
}
\arguments{
\item{x, y}{Vectors}
}
\value{
\itemize{
\item \code{vec_seq_along()} an integer vector with the same size as \code{x}.
\item \code{vec_init_along()} a vector with the same type as \code{x} and the same size
as \code{y}.
}
}
\description{
\code{vec_seq_along()} is equivalent to \code{\link[=seq_along]{seq_along()}} but uses size, not length.
\code{vec_init_along()} creates a vector of missing values with size matching
an existing object.
}
\examples{
vec_seq_along(mtcars)
vec_init_along(head(mtcars))
