addQuantilesColors: Compute quantiles for plotGeneDE function

In a4Base: Automated Affymetrix Array Analysis Base Package

Description

Compute quantiles on mean expression level for plotGeneDE function. Colors of bars in the plot could then be allocated using buckets defined by those quantiles.

Usage

addQuantilesColors(e, ngroups = 3)

Arguments

e	ExpressionSet object to use for computation
ngroups	Number of groups to be created

Details

Number of computed quantiles is equal to (ngroups - 1).

Value

The ExpressionSet object e is returned, with a new column called colorsQuantilesVector in its slot featureData
