\arguments{
\item{x}{[any]\cr
Object to check.}
\item{any.missing}{[\code{logical(1)}]\cr
Are vectors with missing values allowed? Default is \code{TRUE}.}
\item{all.missing}{[\code{logical(1)}]\cr
Are vectors with only missing values allowed? Default is \code{TRUE}.}
\item{len}{[\code{integer(1)}]\cr
Exact expected length of \code{x}.}
\item{min.len}{[\code{integer(1)}]\cr
Minimal length of \code{x}.}
\item{max.len}{[\code{integer(1)}]\cr
Maximal length of \code{x}.}
\item{unique}{[\code{logical(1)}]\cr
Must all values be unique? Default is \code{FALSE}.}
\item{names}{[\code{character(1)}]\cr
Check for names. See \code{\link{checkNamed}} for possible values.
Default is \dQuote{any} which performs no check at all.}
\item{.var.name}{[\code{character(1)}]\cr
Name of the checked object to print in assertions. Defaults to
the heuristic implemented in \code{\link{vname}}.}
\item{add}{[\code{AssertCollection}]\cr
Collection to store assertion messages. See \code{\link{AssertCollection}}.}
\item{info}{[\code{character(1)}]\cr
Extra information to be included in the message for the testthat reporter.
See \code{\link[testthat]{expect_that}}.}
\item{label}{[\code{character(1)}]\cr
Name of the checked object to print in messages. Defaults to
the heuristic implemented in \code{\link{vname}}.}
}
\value{
Depending on the function prefix:
If the check is successful, the functions
\code{assertAtomicVector}/\code{assert_atomic_vector} return
\code{x} invisibly, whereas
\code{checkAtomicVector}/\code{check_atomic_vector} and
\code{testAtomicVector}/\code{test_atomic_vector} return
\code{TRUE}.
If the check is not successful,
\code{assertAtomicVector}/\code{assert_atomic_vector}
throws an error message,
\code{testAtomicVector}/\code{test_atomic_vector}
returns \code{FALSE},
and \code{checkAtomicVector}/\code{check_atomic_vector}
return a string with the error message.
The function \code{expect_atomic_vector} always returns an
\code{\link[testthat]{expectation}}.
}
\description{
An atomic vector is defined slightly different from specifications in
\code{\link[base]{is.atomic}} and \code{\link[base]{is.vector}}:
An atomic vector is either \code{logical}, \code{integer}, \code{numeric},
\code{complex}, \code{character} or \code{raw} and can have any attributes except a
dimension attribute (like matrices).
I.e., a \code{factor} is an atomic vector, but a matrix or \code{NULL} are not.
In short, this is basically equivalent to \code{is.atomic(x) && !is.null(x) && is.null(dim(x))}.
