## RnBeadRawSet-class

### Description

Main class for storing HumanMethylation micorarray data which includes intensity information

### Usage

    RnBeadRawSet(pheno, probes, M, U, M0 = NULL, U0 = NULL,
      bead.counts.M = NULL, bead.counts.U = NULL, p.values = NULL,
      qc = NULL, platform = "450k", beta.offset = 100,
      summarize.bead.counts = TRUE, summarize.regions = TRUE,
      region.types = rnb.region.types.for.analysis("hg19"),
      useff = rnb.getOption("disk.dump.big.matrices"), ffcleanup = FALSE)

### Arguments

`pheno` | Phenotypic data.
`probes` | `character` vector of Infinium(R) probe identifiers
`M` | Matrix of intensities for the probes measuring the abundance of methylated molecules
`U` | Matrix of intensities for the probes measuring the abundance of unmethylated molecules
`M0` | Matrix of "out-of-band" intensities for the probes measuring the abundance of methylated molecules
`U0` | Matrix of "out-of-band" intensities for the probes measuring the abundance of unmethylated molecules
`bead.counts.M` | Matrix of bead counts per probe.
`bead.counts.U` | Matrix of bead counts per probe.
`p.values` | Matrix of detection p-values.
`qc` | ...
`platform` | `character` singleton specifying the microarray platform: `"450k"` corresponds to HumanMethylation450 microarray, and `"27k"` stands for HumanMethylation27.
`beta.offset` | A regularization constant which is added to the denominator at beta-value calculation
`summarize.bead.counts` | If `TRUE` the coverage slot is filled by summarizing the `bead.counts.M` and `bead.counts.U` matrices. For type I probes the summarization is done using `min` operation, while for type II probes the bead counts should be identical in both supplied matrices
`summarize.regions` | ...
`region.types` | A `character` vector specifying the region types, for which the methylation infromation will be summarized.
`useff` | If `TRUE` the data matrices will be stored as `ff` objects
`ffcleanup` | If `TRUE` and disk dumping has been enabled the data of the input `ff` objects will be deleted
