Ranking genes by signal to noise ratio
Description
Ranking genes by signal to noise ratio according to their expression data.
Usage
rank_by_s2n(expmat, label)
Arguments
expmat |
A matrix of gene expression data. Each row is a gene and each column is a sample.
|
label |
An integer vector of encoded pheotypes. Its value is 0 and 1. Its length should match the column number of expression matrix.
|
Value
A vector of rank of each gene according to signal to noise ratio.
Examples
expdat <- matrix(rnorm(500), nrow = 25, ncol = 20)
label <- rep(c(0, 1), 10)
ranklist <- rank_by_s2n(expdat, label)
