rsd_filter {structToolbox} | R Documentation |
An RSD filter calculates the relative standard deviation (the ratio of the mean to the standard deviation) for all features. Any feature with an RSD lower than a predefined threshold is excluded.
rsd_filter(rsd_threshold = 20, qc_label = "QC", factor_name, ...)
