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
hi Martin,
along the lines of the situation that Kasper describes, my use case is
that GSVA transforms a matrix of expression values of genes-by-samples
into a matrix of summary expression values of pathways-by-samples. When
the input is an 'ExpressionSet' object, GSVA simply does something
Robert: The alternative to using exprs- is to instantiate a new object,
just copying the old phenodata.

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

On Fri, Jan
No Robert, in my opinion you did the right thing. You're right to expect
the replacement operation to do the right thing and it is a bug that it
doesn't work.
