Dear R-users,
I'm developing a package that heavily depends on another package
released under the GPL-2 license.
Are you including code from that package in yours, or just making use of
it? The former requires that you follow all the GPL rules about your
own. If you just use their package, then license your package any way
you like.
In addition, some few functions depends on other packages released
under the following licences (as described in the corresponding pages
of http://cran.r-project.org/web/packages/):
GPL
GPL >=2.
I want to release my package under a GPL >= 2 license, and after
reading the section 1.1.1 of the R-exts manual and looking at the
compatibility matrix found on http://gplv3.fsf.org/dd3-faq, I'm still
in doubt if I can do that.
I would appreciate if you could tell me if can I release my package
under a GPL >= 2 license considering the aforementioned licenses ?
Finally, a general question:
When a package is released under GPL >=2, does it mean that the terms
of the GPL-3 license apply or not ?
I believe that's an offer to license under whatever version of the GPL
(from 2 up) that the person using your code chooses. If GPL-3 offers
something that GPL-2 doesn't (e.g. compatibility with other GPL-3 code),
they can use that. If GPL-3 places restrictions they don't like (e.g.
incompatibility with GPL-2 code), they can use GPL-2.

Thanks in advance for any help.
