Hi Daren, You should always be using the very latest version of R (2.8.1 in this case) since the minor revisions are supposed to indicate bug fixes and not additional functionality (added functionality is supposed to go into the development branch). For Bioconductor releases we do not use a minor version number because Bioconductor is not a a single thing the way that R is, but is instead a collection of packages. We synchronize our release 2.3 to go with R 2.8.1 by building all the software packages in Bioconductor nightly. If for some reason a bug fix in R were to cause a problem in one of our packages, then we will update the affected package and bump the minor version number of that package to indicate that there had been a bug fix in it. You can then use sessionInfo() to see if the version numbers on your packages are the latest ones that are available for your particular release of bioconductor, or you can just use biocLite() and update.packages() to automatically update your packages to the very latest available as described here: http://www.bioconductor.org/docs/install/ Marc Daren Tan wrote: > Please clarify my understanding. > > When R version 2.8.0 was released, all packages in Bioconductor version 2.3 was built with it. During this period, any installation of packages in bioconductor 2.3 did not give any warnings. With the minor release R version 2.8.1, Bioconductor version 2.3 was rebuilt with it.

I only noticed the warning message today, and fear that my R or bioconductor is broken. Please give me some assurance it is working fine.
