addQuantilesColors: Compute quantiles for plotGeneDE function

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

ExpressionSet object to use for computation

ngroups

Number of groups to be created

Value

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

Details

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

Examples

Run this code

if (require(ALL)){
    data(ALL, package = "ALL")
    ALLQ <- addQuantilesColors(ALL)
    fData(ALLQ)
  }
