}
\arguments{
\item{x}{[any]\cr
Object to check.}
\item{mode}{[\code{character(1)}]\cr
Storage mode of the array. Arrays can hold vectors, i.e. \dQuote{logical},
\dQuote{integer}, \dQuote{integerish}, \dQuote{double}, \dQuote{numeric}, \dQuote{complex},
\dQuote{character} and \dQuote{list}. You can also specify \dQuote{atomic}
here to explicitly prohibit lists. Default is \code{NULL} (no check).
If all values of \code{x} are missing, this check is skipped.}
\item{any.missing}{[\code{logical(1)}]\cr
Are missing values allowed? Default is \code{TRUE}.}
\item{d}{[\code{integer(1)}]\cr
Exact number of dimensions of array \code{x}.
Default is \code{NULL} (no check).}
\item{min.d}{[\code{integer(1)}]\cr
Minimum number of dimensions of array \code{x}.
Default is \code{NULL} (no check).}
\item{max.d}{[\code{integer(1)}]\cr
Maximum number of dimensions of array \code{x}.
Default is \code{NULL} (no check).}
\item{null.ok}{[\code{logical(1)}]\cr
If set to \code{TRUE}, \code{x} may also be \code{NULL}.
In this case only a type check of \code{x} is performed, all additional checks are disabled.}
\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{assertArray}/\code{assert_array} return
\code{x} invisibly, whereas
\code{checkArray}/\code{check_array} and
\code{testArray}/\code{test_array} return
\code{TRUE}.
If the check is not successful,
\code{assertArray}/\code{assert_array}
throws an error message,
\code{testArray}/\code{test_array}
returns \code{FALSE},
and \code{checkArray}/\code{check_array}
return a string with the error message.
The function \code{expect_array} always returns an
\code{\link[testthat]{expectation}}.
