Btw, I hacked together a subset() method for GenomicRanges yesterday. It respects the metadata columns. Someone could probably come up with some reason why that violates the conceptual foundations of something, but I find it useful. So you could do: subset(gr, over == 2) Will commit shortly.

Hi Hervé, That's what I ended up doing, actually. One question that came up though is whether we want to support 2D subsetting of all (or at least most) Vector objects, in the same manner as GRanges. I think it would work, how about you?

If by 2D subsetting you're referring to gr[i,j], I'm opposed to it. I think it's a mistake to try to put the 2D *low-level* API on top of objects that are conceptually not 2D objects. The current situation where we have 2D subsetting already work on both GRanges and GRangesList objects but do different things is messy and tells me that we shouldn't have provided this in the first place. Sounds like the gr$foo story again. Hopefully gr$foo will remain a 1 time exception. I think subset() is already giving you something similar to the 2D subsetting right?

The [i,meta_j] syntax is probably not very useful (at least in my experience), so I wouldn't favor it to the extent of $meta_name. For now, subset(select=) is probably sufficient.

In base R, subscripting with NA leads to > x = 1:5 > x[NA] [1] NA NA NA NA NA which makes a weird sense (recycling a length 1 NA) but I/GRanges don't support the notion of NA-ranges.
