)
}
\arguments{
\item{x}{An NxK matrix-like object.}

\item{w}{A \code{\link{numeric}} vector of length K (N) that specifies by
how much each element is weighted.}

\item{rows}{A \code{\link{vector}} indicating the subset of rows
(and/or columns) to operate over. If \code{\link{NULL}}, no subsetting is
done.}

\item{cols}{A \code{\link{vector}} indicating the subset of rows
(and/or columns) to operate over. If \code{\link{NULL}}, no subsetting is
done.}

\item{na.rm}{If \code{\link[base:logical]{TRUE}}, \code{\link{NA}}s
are excluded first, otherwise not.}

\item{useNames}{If \code{\link{NA}}, the default behavior of the function about naming support is remained. If \code{\link{FALSE}}, no naming support is done. Else if \code{\link{TRUE}}, names attributes of result are set.}
}
\value{
Returns a \code{\link{numeric}} \code{\link{vector}} of length N (K).
