RNADegradation {AffyRNADegradation} | R Documentation |
Given an AffyBatch object, the function RNADegradation
computes the probe positional bias and several statistical parameters,
including a robust and accurate measure of RNA degradation. Probe
intensities are corrected for the bias for each sample within the
AffyBatch
object.
