\title{Calculates the interquartile range for each row (column) of a matrix-like
object}
\usage{
\S4method{colIQRs}{xgCMatrix}(x, rows = NULL, cols = NULL, na.rm = FALSE, useNames = TRUE)
\S4method{rowIQRs}{xgCMatrix}(x, rows = NULL, cols = NULL, na.rm = FALSE, useNames = TRUE)
}
\arguments{
\item{x}{An NxK matrix-like object.}
\item{rows, 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]{TRUE}}, missing values
(\code{\link[base]{NA}} or \code{\link[base]{NaN}}) are
omitted from the calculations.}
\item{useNames}{If \code{\link{TRUE}} (default), names attributes of result are set. Else if \code{\link{FALSE}}, no naming support is done.}
}
\value{
Returns a \code{\link{numeric}} \code{\link{vector}} of length N (K).
}
\description{
Calculates the interquartile range for each row (column) of a matrix-like
object.
}
\details{
The S4 methods for \code{x} of type \code{\link{matrix}},
\code{\link{array}}, \code{\link{table}}, or \code{\link{numeric}} call
\code{matrixStats::\link[matrixStats]{rowIQRs}} /
\code{matrixStats::\link[matrixStats]{colIQRs}}.
}
\examples{
mat <- matrix(rnorm(15), nrow = 5, ncol = 3)
mat[2, 1] <- NA
mat[3, 3] <- Inf
mat[4, 1] <- 0
print(mat)
rowIQRs(mat)
colIQRs(mat)
}
\seealso{
\itemize{
\item \code{matrixStats::\link[matrixStats]{rowIQRs}()} and
\code{matrixStats::\link[matrixStats:rowIQRs]{colIQRs}()} which are used
when the input is a \code{matrix} or \code{numeric} vector.
