hi Kasper,
you're right. i should have done this upfront, this was too much S4
magic to be true :)
cheers,
robert.

Robert: The alternative to using exprs<- is to instantiate a new object,
just copying the old phenodata.

Unfortunately, you may want to be careful about making it too robust
(depending on what you mean). For example filtering methods could very
well be seen as replacing one matrix with a smaller one. Not sure if
these
methods use exprs<-, but that is probably how I would do it.
What would be better is if in the process of doing the replacement, the
other slots are harmonized in a relevant way. That would require row
names
on the replacement matrix.
I suspect I also have used exprs<- to change the number of rows of an
ExpressionSet during analyses, when there were no featureData. Not that I
mind changing, but it may not be unusual "out there."
