[Rd] Closed-source non-free ParallelR ?

Hi Matt,

Do you know if a project like R(D)COM/Statconn can changing their
license to make it closed-source? (www.statconn.com &
http://rcom.univie.ac.at/ )

There was discussion on the RCom board about such changes earlier this
year as they move toward commercialization. If you're not familiar it's
a package/windows COM program that allows EXCEL and other win apps to
interact directly with R. They have also generated an installer package
which installs R at the same time as their software. It makes 'R'
effectively disappear from the windows box.

Would distribution of that software also have to stay as GPL not LGPL?
As R effectively sits within the proprietary system of Statconn.

Regards, Fraser

Because the BSD is an open source license compatible with GPL.  See 
http://www.fsf.org/licensing/licenses/index_html#GPLCompatibleLicenses

> derivative work
Points taken. It may not be derivation in the sense of modification,
more in 
the sense of using R as a library :
http://www.gnu.org/licenses/gpl-faq.html#GPLInProprietarySystem
http://www.gnu.org/licenses/gpl-faq.html#IfLibraryIsGPL
http://www.gnu.org/licenses/gpl-faq.html#LinkingWithGPL
http://www.gnu.org/licenses/gpl-faq.html#IfInterpreterIsGPL  (paragraphs
3 
and 4 in particular)

R, and base functions written in R, are GPL not LGPL.  In the context of
the 
FAQ above, do your packages use base functions ?
http://www.gnu.org/philosophy/why-not-lgpl.html

The first R FAQ (1.1) states that R is released under GPL version 2 or
any 
later version.
At the end of the GPL (both v2 and v3) it says "This General Public
License 
does not permit incorporating your program into proprietary programs. If

your program is a subroutine library, you may consider it more useful to

permit linking proprietary applications with the library. If this is
what 
you want to do, use the GNU Lesser General Public License instead of
this 
License."

> there are certainly many existing R packages with non-free/non-open 
> licenses
They could be in breach too. The fact their licenses are like that does
not 
in itself mean they are compliant with the GPL. R FAQ 2.11 defers to
legal 
counsel - it mentions such licenses but it states no opinion about them
as 
far as my reading goes. At least the source code of those packages is 
available for download. REvolution appear to be going one step further
i.e. 
bundling R with their proprietary packages and selling the work as a
whole.

Could someone from the R Foundation or the FSF step in and clarify the 
situation please ?   If in your opinion it is all fine what people are 
doing, why not release R under the LGPL for clarity ?

Regards, Matthew

Patrick made all the points that I was going to make (thanks,
Patrick), but I wanted to reinforce one point that may be the source
of the confusion: ParallelR is not a modified version of R: ParallelR
is a suite of ordinary R packages that run on top of the R engine like
any other package. The R code and Python code in these packages were
written entirely by REvolution Computing staff (including Patrick),
and do not contain any code (derived or otherwise) from the R project.

In retrospect, the name ParallelR may be somewhat confusing in this
sense...
