rowQ: A function to compute empirical row quantiles.

Description

This function computes the requested quantile for each row of a matrix, or of an ExpressionSet.

Usage

rowQ(imat, which)
rowMax(imat)
rowMin(imat)

Arguments

imat

Either a matrix or an ExpressionSet.

which

An integer indicating which order statistic should be returned.

Value

A vector of length equal to the number of rows of the input matrix containing the requested quantiles.

Details

rowMax, rowMin and rowMedians simply call rowQ with the appropriate argument set.

The argument which takes values between 1, for the minimum per row, and ncol(imat), for the maximum per row.
