Is there any way to get the information about beads number contributing in signal for probe from MethylSet (minfi package)? I know it is possible for data in shape of RGChannelSetExtended by slot: rgSet@assayData$NBeads, but I want to remove probes with less than 3 beads contributing and I perform few steps before that which requires to operate on MethylSet.

I would appreciate any suggestion.

Kind regards, Agata
