Hi all,
I implemented a subclass of SummarizedExperiment from the GenomicRanges package.
When I call cbind() on two objects of my subclass, I get an object of class
SummarizedExperiment and not of my own class. So I have to re-implement cbind()
in order to avoid this unwanted class coercing. This is not the case for, e.g.,
combine() for class eSet. I am wondering whether it would make sense to change
the implementation of cbind() (and also rbind() etc.) for SummarizedExperiment
in order to make class inheritance more convenient?
Hi Hans -- Thanks for the report, this is fixed in 1.17.35 for cbind and rbind;
if there are other methods with similar problems please don't hesitate to let us
know.

[1] "A"
