Copy number estimates are susceptible to systematic differences between
groups of samples that were processed at different times or by
different labs. While 'batch' is often unknown, a useful surrogates
is often the scan date of the arrays (e.g., the month of the calendar
year) or the 96 well chemistry plate on which the samples were arrayed
during lab processing.
Usage
batch(object)
batchNames(object)
batchNames(object) <- value
Arguments
object
An object of class CNSet.
value
For 'batchNames', the value must be a character string corresponding
of the unique batch names.
Value
The method 'batch' returns a character vector that has the same
length as the number of samples in the CNSet object.
