\title{Calculates the minimum and maximum for each row (column) of a matrix-like
object}
\usage{
\S4method{colRanges}{dgCMatrix}(x, rows = NULL, cols = NULL, na.rm = FALSE)
\S4method{rowRanges}{dgCMatrix}(x, rows = NULL, cols = NULL, na.rm = FALSE)
}
\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{na.rm}{If \code{\link[base:logical]{TRUE}}, \code{\link{NA}}s
are excluded first, otherwise not.}
}
\value{
a \code{\link{numeric}} \code{Nx2} (\code{Kx2})
\code{\link{matrix}}, where N (K) is the number of rows (columns) for
which the ranges are calculated.
}
\description{
Calculates the minimum and maximum 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::rowRanges}
/ \code{matrixStats::colRanges}.
}
\examples{
mat <- matrix(rnorm(15), nrow = 5, ncol = 3)
mat[2, 1] <- NA
mat[3, 3] <- Inf
mat[4, 1] <- 0
print(mat)
rowRanges(mat)
colRanges(mat)
}

\itemize{
\item \code{matrixStats::\link[matrixStats]{rowRanges}()} and
\code{matrixStats::\link[matrixStats:rowRanges]{colRanges}()} which are
used when the input is a \code{matrix} or \code{numeric} vector.
