Top quantile expression-variance genes

Select genes residing in the top quantile according to the variance of their expression across the stages

Usage

TopVarianceGenes(ExpressionSet, p = 0.99)

Arguments

ExpressionSet

A standard ExpressionSet

p

The quantile probability. Default is p = .99

Value

a character vector containing the gene ids residing in the top variance expression quantile

Examples

# reading a standard PhyloExpressionSet
data(PhyloExpressionSetExample)

# select genes with highest variance (top 5%)  
genes.top_variance <- TopVarianceGenes(PhyloExpressionSetExample, p=.95)
