Bug#800891: r-cran-afex violates the GPL2

[Jonathon Love]

Package: ftp.debian.org,r-cran-afex
Version: 0.14-2-1
Severity: serious
Tags: upstream
Justification: Policy 2.3

Dear Maintainer,

I believe the r-cran-afex package violates the GPL. It is released under GPL3+, however it has GPL2-only dependencies (r-cran-stringr, r-cran-coin, r-crain-lsmeans), and it calls functions from these packages directly.

The nature of the interaction (function calls) means that r-cran-afex and its dependencies constitute a single work, and not two separate programs, as per the GPL faq:
