Hello, I'm working on dna methylation microarray. I need to merge two sets into one set. > rawData $v1 TilingFeatureSet (storageMode: lockedEnvironment) assayData: 2197815 features, 59 samples element names: channel1, channel2 protocolData rowNames: LT290677RU_D1_2011-02-16 LT286300LU_D1_2010-07-24 ...

How can I merge them to create new dataset?
