Subset an RGChannelSet by CpG loci.

keepControls = TRUE, keepSnps = TRUE)
|
rgSet |
An object of class |
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.
