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.
