[Bioc-sig-seq] Consolidate AlignedRead objects

[Ivan Gregoretti]

Hello everybody,

Is there any memory efficient way to consolidate multiple AlignedRead
objects into one?


Example:

Lets say that I have 10 AlignedRead instances, 10 million tags each.
Lets call those instances aln01 through aln10.

I can consolidate two of them like this:

aln <- append(aln01, aln02)

Can I consolidate all AlignRead instances in a single shot? Something like this:

aln <- superDuperConsolidator(aln01, aln02, aln03, ..., aln10)

Thank you,

Ivan
