[Bioc-devel] ggbio: Support of object inheriting from 'GRanges'

Hi,

while ggbio work well for 'GRanges' objects, it is not able to deal with 
objects inheriting from a 'GRanges', e.g. a 'VRanges' object:

library(ggbio)
library(GenomicRanges)
library(VariantAnnotation)

gr = GRanges("1", IRanges(1, 10))
vr = as(gr, "VRanges")

autoplot(gr) ## works
autoplot(vr) ## breaks

The simple workaround would be to convert back to a 'GRanges' first by 
hand.  But shouldn't ggbio be able to handle these cases?  Is this 
related to the different defaults of strands between GRanges and VRanges?

Best wishes
Julian
