An R package to ensure reproducibility of microarray-based classification signatures
docval is an R/Bioconductor compliant package allowing to document preprocessing parameters from normalization as well as from probe-set summary as needed on Affymetrix platforms. This enables users to generate classification signatures which are reproducible on data generated after the study used to learn the signature. Moreover, it enables investigators of very large studies to normalize their data in several batches without loosing comparability over time.
