Description: Precise measurements are important for epigenome-wide
        studies investigating DNA methylation in whole blood samples,
        where effect sizes are expected to be small in magnitude. The
        450K platform is often affected by batch effects and proper
        preprocessing is recommended. This package provides functions
        to read and normalize 450K '.idat' files. The normalization
        corrects for dye bias and biases related to signal intensity
        and methylation of probes using local regression. No adjustment
        for probe type bias is performed to avoid the trade-off of
        precision for accuracy of beta-values.
