\title{Get names of a vector}
\usage{
names2(x)

names2(x) <- value
}
\arguments{
\item{x}{A vector.}

\item{value}{New names.}
}
\description{
\code{names2()} always returns a character vector, even when an
object does not have a \code{names} attribute. In this case, it returns
a vector of empty names \code{""}. It also standardises missing names to
\code{""}.

The replacement variant \verb{names2<-} never adds \code{NA} names and
instead fills unnamed vectors with \code{""}.
}
\examples{
names2(letters)

# It also takes care of standardising missing names:
x <- set_names(1:3, c("a", NA, "b"))
names2(x)

# Replacing names with the base `names<-` function may introduce
# `NA` values when the vector is unnamed:
x <- 1:3
names(x)[1:2] <- "foo"
names(x)

# Use the `names2<-` variant to avoid this
x <- 1:3
names2(x)[1:2] <- "foo"
names(x)
