\title{Size of Matrix}
\description{
Provides the dimensions of \code{X}.
}
\usage{
size(x, k)
}
\arguments{
\item{x}{vector, matrix, or array}
\item{k}{integer specifying a particular dimension}
}
\details{
Returns the number of dimensions as \code{length(x)}.
Vector will be treated as a single row matrix.
}
\value{
vector containing the dimensions of \code{x}, or the \code{k}-th dimension
if \code{k} is not missing.
}
\note{
The result will differ from Matlab when \code{x} is a character vector.
}

\examples{
size(1:8)
size(matrix(1:8, 2, 4)) # 2 4
size(matrix(1:8, 2, 4), 2) # 4
size(matrix(1:8, 2, 4), 3) # 1
