Hi Nico,
It seems reasonable indeed to support rowRanges<- on
SummarizedExperiment0. It might be a little bit surprising for the
user that the setter changes the class of the object but it looks
like a perfectly legit situation for doing so here. Also there are
some precedents:
> x <- 1:5
> x[1] <- "a"
> x
[1] "a" "2" "3" "4" "5"
and:
library(Biostrings)
dna <- DNAString("GGATTAAA")
class(dna) # DNAString
masks(dna) <- Mask(length(dna), 2, 5)
class(dna) # MaskedDNAString
I'll add this, unless someone has a better idea?
Thanks,
H.

Hej alla!
In the simpleRNASeq function of the easyRNASeq package, I start by instantiating a
SummarizedExperiment object not initially providing the rowRanges. This results in the creation of an
object of the class SummarizedExperiment0. When later, once I have validated the annotation, I try to
extend the rowRanges of my SummarizedExperiment object, I get an error message that
"rowRanges<-" is not implemented for signature "SummarizedExperiment0,
GRangesList".
I'm now wondering if this has been omitted on purpose for SummarizedExperiment0
objects or is not yet implemented. The reason I'm wondering is because there is
the possibility to cast a SummarizedExperiment0 object as a
RangedSummarizedExperiment (which is my current work-around), but I'm wondering
if that's the best way to go.
I don't have access to my Rsession right now, so no sessionInfo(), but I'm
using R3.2.1 on OSX 10.10.3 (Yosemite), and the latest devel packages (updated
today; SummarizedExperiment version is 0.3.0).
Cheers,
Nico
