That's what sort(), order(), rank() do by default: they sort by seqnames
first, then by start, then by end, and finally by strand.

Ok. So the candidates are:

  (a) standardizeSeqinfo(gr) <- "hg19"

  (b) gr <- standardizeSeqinfo(gr, "hg19")

  (c) standardizeGenome(gr) <- "hg19"

  (d) gr <- standardizeGenome(gr, "hg19")

  (e) seqinfo(gr) <- "hg19"

Is there a risk of confusion with keepStandardChromosomes where
"standard" means a very different thing? I'll add 2 more:

  (f) normalizeSeqinfo(gr) <- "hg19"

  (g) gr <- normalizeSeqinfo(gr, "hg19")

Anyway, we're not here yet. As pointed in an earlier post, there are
still some missing pieces to complete the puzzle.

Thanks,
H.
