Dear Yaoyong,
Can you remove the R version dependency from your DESCRIPTION file
entirely? That will eliminate the warning, but will also not suggest to
users that they need a newer version of R than is necessary. R 2.3.0 was
released in 2006, so it seems highly unlikely that anyone would be
currently trying to use an R version older than that.
Lori's answer seems to be more about the R version you should be using
to test your package, which should indeed be current, but that is
different than the minimum R version required to run the package at all.
I know Bioconductor encourages users to stay up-to-date with R versions
and does not guarantee that older versions will work with all packages,
but I think there is still some utility in letting users know which
packages depend on recent versions of R, and which packages can be
expected to work with older versions.

Dear Lori,
many thanks for your detailed explanations. I think that it makes sense
from Bioconductor maintenance's point of view to require that the R version
of a package should be the same of the R version in a Bioconductor release
which includes the package, because it's the safest option. On the other
hand, I still think that this requirement put some unnecessary limit on the
scope of the R version which a package can be used with. For example, as
the package creator I know that my package can work with R from 2.3.0 and
upward, including the version 3.4 that the current Bioconductor used, then
why should I have to restrict the R version to 3.4 and upward. I guess that
it's the package creator's responsibility to determine which R version(s)
their packages depend on? It seems to me that there is a R version problem
between the package and the Biocondonctor only when the R versions that a
package specifies does not include the R version of a Bioconductor release
which the package is supposed to be included in.
I think that it probably makes no much difference in practice between what
I think it should be and the current practice in Bioconductor, as one can
easily upgrade the R to the latest version with no cost. But I hope you can
see the difference in theory.
Best regards,
Yaoyong

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
