Fold Change Calculations

Description

A function to calculate the log-ratios stratified by which ALE groups yield the comparison. They are stratified by which bins are being compared to produce the given fold change.

Usage

spkBox(object, spkSlopeOut, fc = 2, tol = 3, reduce=TRUE)

Arguments

object a SpikeInExpressionSet object
spkSlopeOut the output of the spkSlope function
fc the fold change of interest
tol the precision (number of digits after decimal point) in fc
reduce if TRUE the number of points plotted in the null bins is reduced

Details

This function requires the output of spkSlope.

Value

A list with the log-ratios separated by ALE strata comparison.
