Hi,
I am unable to find any examples of facet_gr argument to autoplot.

It is mentioned in http://bioconductor.org/packages/2.12/bioc/manuals/ggbio/man/ggbio.pdf on page 9 as:

Sometime, we need to view different regions, so we also have a facet_gr argument which
accept a GRanges. If this is provided, it will override the default seqnames and use provided
region to facet the graphics, this might be useful for different gene centric views.

However there is no further example of its use, and it does not appear in the list of formals, and it does not appear at all in http://bioconductor.org/packages/2.12/bioc/vignettes/ggbio/inst/doc/ggbio.pdf

And the only google hits suggest this feature is out deprecated.

Am I missing something?

Is there a contemporary equivalent?  Is there some way to facet on genomic range?  Any examples out there?

Thanks,
