Re: autoplot() in ggbio package for txdb object

Hi Rebecca,

So sorry for the late reply, in case I forget next time, please feel free
to leave your question/feedback in github issues page backlog
<https://github.com/tengfei/ggbio/issues>. I will work on those issues when
I got time.

For you question, yes, I just confirmed this is a bug in biovizBase/ggbio
package for exons with no cds, I fixed the released branch
biovizBase(1.12.2) and ggbio(1.12.9) (will fix the devel branch later this
week), please update your packages two days later to see if my fix solved
the problem or not.

thanks again for reporting the bug!

cheers
