spkBox {spkTools} | R Documentation |
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.
spkBox(object, spkSlopeOut, fc = 2, tol = 3, reduce=TRUE)
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 |
This function requires the output of spkSlope.
A list with the log-ratios separated by ALE strata comparison.
