rowQ

A function to compute empirical row quantiles.

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.
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.

Value

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