That would probably depend on the license that the file is under, and the
license of the package you want to embed it in. [Goes looking:
BSD-3-clause. That means that you need to figure out if/how you can mix "your
code" in BSD-2 per your earlier mail with BSD-3 per the link.
Now: these things have been discussed ad nauseum over the 20+ years during
which Open Source / Free Software has become so much more prominent. Many
resources exists, see eg http://www.gnu.org/licenses/gpl-faq.en.html and
references therein, as well as http://opensource.org/licenses (which is
almost where your URL above links to as well if you follow its license link).
I am not sure we add value if we direct this list ---- freshly created to
address _packaging problems for R_ to yet another venue debating licenses and
mechanics. There is _nothing_ R specific in that question.
