}
\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 no non-missing values allowed? Default is \code{TRUE}.
Note that empty vectors do not have non-missing values.}
\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.
Note that you can use \code{\link{checkSubset}} to check for a specific set of names.}
\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{assertAtomic}/\code{assert_atomic} return
\code{x} invisibly, whereas
\code{checkAtomic}/\code{check_atomic} and
\code{testAtomic}/\code{test_atomic} return
\code{TRUE}.
If the check is not successful,
\code{assertAtomic}/\code{assert_atomic}
throws an error message,
\code{testAtomic}/\code{test_atomic}
returns \code{FALSE},
and \code{checkAtomic}/\code{check_atomic}
return a string with the error message.
The function \code{expect_atomic} always returns an
\code{\link[testthat]{expectation}}.
}
\description{
For the definition of \dQuote{atomic}, see \code{\link[base]{is.atomic}}.
Note that `NULL` is recognized as a valid atomic value, as in R versions up to version 4.3.x.
