Description Usage Arguments Details Value Examples

Subset an RGChannelSet by CpG loci.

1 2	subsetByLoci(rgSet, includeLoci = NULL, excludeLoci = NULL, keepControls = TRUE, keepSnps = TRUE)

`rgSet`	An object of class `RGChannelSet` (or `RGChannelSetExtended`).
`includeLoci`	A character vector of CpG identifiers which should be kept.
`excludeLoci`	A character vector of CpG identifiers which should be excluded.
`keepControls`	Should control probes be kept?
`keepSnps`	Should SNP probes be kept?

This task is non-trivial because an RGChannelSet is indexed by probe position on the array, not by loci name.

An object of class RGChannelSet, which some probes removed.

  subsetByLoci(RGsetEx.sub, excludeLoci = loci)
