combine() is the old style way of combining ExpressionSets and friends and is pretty powerful, for example dealing with pData objects with different columns (which is the case for almost all data). It seems to me that cbind() on SummarizedExperiments is much less powerful. Specifically rbind() on DataFrame's (for colData) requires that the two DataFrame's have the same columns. I think this should be addressed. It is not clear to me that rbind() doesn't do the right thing, but in that case perhaps we do need combine() for SummarizedExperiment's and DataFrame's Or perhaps Im doing it wrong. Best, Kasper

Seems like merge() might be the appropriate verb here. On Tue, Jul 12, 2016 at 9:31 AM, Kasper Daniel Hansen
