}
\arguments{
\item{x}{[any]\cr
Object to check.}
\item{strict}{[\code{logical(1)}]\cr
May the vector have additional attributes? If \code{TRUE}, mimics the behavior of
\code{\link[base]{is.vector}}.
Default is \code{FALSE} which allows e.g. \code{factor}s or \code{data.frame}s
to be recognized as vectors.}
\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{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}}.}
}
\value{
Depending on the function prefix:
If the check is successful, the functions
\code{assertVector}/\code{assert_vector} return
\code{x} invisibly, whereas
\code{checkVector}/\code{check_vector} and
\code{testVector}/\code{test_vector} return
\code{TRUE}.
If the check is not successful,
\code{assertVector}/\code{assert_vector}
throws an error message,
\code{testVector}/\code{test_vector}
returns \code{FALSE},
and \code{checkVector}/\code{check_vector}
return a string with the error message.
The function \code{expect_vector} always returns an
\code{\link[testthat]{expectation}}.
