\arguments{
\item{x}{[any]\cr
Object to check.}

\item{lower}{[\code{numeric(1)}]\cr
Lower value all elements of \code{x} must be greater than or equal to.}

\item{upper}{[\code{numeric(1)}]\cr
Upper value all elements of \code{x} must be lower than or equal to.}

\item{finite}{[\code{logical(1)}]\cr
Check for only finite values? Default is \code{FALSE}.}

\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{sorted}{[\code{logical(1)}]\cr
Elements must be sorted in ascending order. Missing values are ignored.}

\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{typed.missing}{[\code{logical(1)}]\cr
If set to \code{FALSE} (default), all types of missing values (\code{NA}, \code{NA_integer_},
\code{NA_real_}, \code{NA_character_} or \code{NA_character_}) as well as empty vectors are allowed
while type-checking atomic input.
Set to \code{TRUE} to enable strict type checking.}

\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{assertNumeric}/\code{assert_numeric} return 
 \code{x} invisibly, whereas
 \code{checkNumeric}/\code{check_numeric} and 
 \code{testNumeric}/\code{test_numeric} return 
 \code{TRUE}.
 If the check is not successful, 
 \code{assertNumeric}/\code{assert_numeric}
 throws an error message, 
 \code{testNumeric}/\code{test_numeric}
 returns \code{FALSE},
 and \code{checkNumeric}/\code{check_numeric} 
 return a string with the error message.
 The function \code{expect_numeric} always returns an
 \code{\link[testthat]{expectation}}.
}
\description{
Vectors of storage type \dQuote{integer} and \dQuote{double} count as \dQuote{numeric}, c.f. \code{\link[base]{is.numeric}}.
To explicitly check for real integer or double vectors, see \code{\link{checkInteger}}, \code{\link{checkIntegerish}} or
\code{\link{checkDouble}}.

\details{
This function does not distinguish between
\code{NA}, \code{NA_integer_}, \code{NA_real_}, \code{NA_complex_}
\code{NA_character_} and \code{NaN}.
