We strongly recommend the version of R that is used on our builders when
building and checking your package. This is also to ensure that the package
dependencies are also in a version that is compatible with a new package. We
can't guarantee that a package will work with a previous version of a
dependency so the best practice is to use the current version of R as we check
against the most recent and current versions of packages for the version of R
and Bioconductor. This is also why we have biocValid and biocLite to make sure
packages are up-to-date and valid for a particular version of R and
Bioconductor. Package can change over time and cause compatibility issues that
are unforseen; R also can change from version to version and cause unforseen
problems.

Subject: EXTERNAL: [Bioc-devel] R version dependence of a new package
Hello,
may I ask a question about the R version dependence?
Currently I am trying to submit a package to Bioconductor repository. When
my package was built at bioconductor.org, I got a warning message
"* WARNING: Update R version dependency from 2.3.0 to 3.4."
So I changed the R dependency to 3.4 in my DESCRIPTION file, and
consequently the warning message disappeared. However, as one result of the
change, my package cannot be loaded and run in R whose version is earlier
than 3.4. On the other hand, my package actually doesn't need the R version
>= 3.4. For example, it works perfectly with R version 3.2.2 which was
installed in my computer. S my question is why the package builder at
bioconductor.org wanted my package to update the R version to 3.4.
Best regards,
Yaoyong
