maxNoisyGenes: Function for extracting genes maximal variability
Description
This function extracts genes with maximal variability in a cluster or in the entire data set.
Usage
maxNoisyGenes(noise, cl = NULL, set = NULL)
Value
Vector with average gene expression variability in decreasing order, computed across all cells or only cells in a set of clusters (if cl and
set are given.
Arguments
noise
List object with the background noise model and a variability matrix, returned by the compNoise function.
cl
List object with clustering information, returned by the graphCluster function. Default is NULL.
set
Postive integer number or vector of integers corresponding to valid cluster numbers. Noise levels are computed across all cells in this subset of clusters. Default is NULL and noise levels are computed across all cells.
