In some cases, the COPYING file is included in the main source package folder, so that it is available in the distribution of the package source tarball, but as Dirk noted, it is not installed. You can then include a LICENCE file in the 'inst' directory, where that file has content along the lines of the following (based upon V&R's MASS) for GPL2: Copyrights == Licence === This is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; version 2. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. Files share/licenses/GPL-2 in the R (source or binary) distribution is a copy of version 2 of the 'GNU General Public License'. These can also be viewed at http://www.r-project.org/licenses/ So in the above case, the LICENCE file will be available in both the source and binary/installed versions of the package, but without duplicating the content of the full COPYING file.

I used to mention that location in the License: line of the DESCRIPTION file, after GPL (>=2). But some versions ago, that line got standardised and now it is no longer possible to put additional text onto that line. I guess you could just add a line LicenceLocation: As far as I understand the documentation, you are free to add additional lines beyond those described in "Writing R Extensions" to the DESCRIPTION file. Some entries described in the manual are optional and for those that are not some restrictions may apply that have to be followed. Personally, I decided not to put any such reference into the DESCRIPTION file of my packages as I guess that people who worry about the lisence will either look into the source package (where I have a copy) or know how to find one. :) HTH.

Re: [R] declaring GPL license
Thanks everyone. Now I know that I should not include another copy of the
license, but where should I refer to the copies on
http://www.r-project.org/Licenses/? In the DESCRIPTION file?

| Yep. I stand corrected on that point. :-)
As a minor addition, keeping COPYING in the top-level (as per my earlier
email) appears to satisfy the wishes of those at the FSF (include COPYING) as
well as R Core (do not install COPYING)) -- where files in inst/ will always
get installed. It's also simply more visible at the top-level.

But that would be against the wishes of R core, from the "Writing R
Extension" manual:
Whereas you should feel free to include a license file in your
source distribution, please do not arrange to @emph{install} yet
another copy of the @acronym{GNU} @file{COPYING} or
@file{COPYING.LIB} files but refer to the copies on
@url{http://www.r-project.org/Licenses/} and included in the
@R{} distribution (in directory @file{share/licenses}).
:)
