Package: r-base-dev
Version: 3.0.0-2
Severity: wishlist
Tags: patch
Hi Dirk,
in light with the recent discussion and suggestions about the rare API
breakages with R, I would like to propose the following:
- R provides a virtual package, for instance, 'r-api-3'. This name is
modified (for instance to 'r-api-4', 'r-api-3b', etc.) when
backward-incompatible changes are introduced.
- R library packages depend on that virtual package through the already
implemented R:Depends system, replacing the current convention of
depending on any version equal or superior to one of the r-base package
used at build time.
This can be done with the attached patch, that I tested locally.
Have a nice week-end,
