[R] Question about the license of an R package

[Mauricio Zambrano]

Dear R-users,

I'm developing a package that heavily depends on another package
released under the GPL-2 license.

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 ?


Thanks in advance for any help.

Mauricio
