degenes: Recovering differencially expressed features.

Description

Recovering differencially expressed features for a given threshold from noiseq or noiseqbio output objects.

Usage

degenes(object, q = 0.95, M = NULL)

Arguments

object

Object of class Output.

q

Value for the probability threshold (by default, 0.95).

M

String indicating if all differentially expressed features are to be returned or only up or down-regulated features. The possible values are: "up" (up-regulated in condition 1), "down" (down-regulated in condition 1), or NULL (all differentially expressed features).

Value

A matrix containing the differencially expressed features, the statistics and the probability of differential expression.

Examples

## Load the object mynoiseq generated by computing differential expression probability with noiseq() on Marioni's data:
data(noiseq)

## Third, use degenes() function to extract differentially expressed features:
mynoiseq.deg = degenes(mynoiseq, q = 0.8, M = NULL)
