There is a combine method for eSets. So if you have your datasets already
as eSets, it would be as simple as
combined.eset <- combine(eset1, eset2)
And you can use this recursively for more than two esets.
Beware of some constraints though. From the documentation for eSet:
Combine two eSet objects. To be combined, eSets must have identical
numbers of featureNames, distinct sampleNames, and identical
