x,
rows = NULL,

}
\arguments{
\item{x}{An NxK matrix-like object.}
\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{probs}{A numeric vector of J probabilities in [0, 1].}
\item{na.rm}{If \code{\link[base:logical]{TRUE}}, \code{\link{NA}}s
are excluded first, otherwise not.}
\item{type}{An integer specifying the type of estimator. See
\code{stats::\link[stats]{quantile}()}. for more details.}
\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.}
\item{drop}{If \code{TRUE} a vector is returned if \code{J == 1}.}
}
\value{
a \code{\link{numeric}} \code{NxJ} (\code{KxJ})
\code{\link{matrix}}, where N (K) is the number of rows (columns) for
which the J values are calculated.
}
\description{
Calculates quantiles for each row (column) of a matrix-like object.
}
\details{
The S4 methods for \code{x} of type \code{\link{matrix}},
\code{\link{array}}, or \code{\link{numeric}} call
\code{matrixStats::rowQuantiles}
/ \code{matrixStats::colQuantiles}.
}
\examples{
mat <- matrix(rnorm(15), nrow = 5, ncol = 3)
mat[2, 1] <- NA
mat[3, 3] <- Inf
mat[4, 1] <- 0
print(mat)

\itemize{
\item \code{matrixStats::\link[matrixStats]{rowQuantiles}()} and

are used when the input is a \code{matrix} or \code{numeric} vector.
