After R 2.15, R release cycle falls into annual release instead of semi-annual release cycle, at the same time, Bioconductor project still follows semi-annual release cycle. So now you can install both released and developmental version for the same version of R.
In your R session, please run following code to install released version of ggbio, but if you are using developmental version of R, you will get developmental version of ggbio automatically. Because what you get depends on the bioconductor installer, which is implemented in package BiocInstaller and its version decides which version of Bioconductor you got.To check homepage on bioconductor
