What should happen is that they get an ExpressionSet with only three
features, but the same samples (arrays x colours = columns of exprs and
rows of phenoData). The different colours are stored sideways, so unless
I really need to catch up with recent changes in Expression specs, I
think the row-subsetting does what we want.
Best wishes
