[R-gui] GPL licensing issues with a commercial R GUI
I am not a lawyer, but at important distinction here is what one means by "linked". You're not linking against R if you just run some R code through it and capture the output for example. This is how Brodgar, for example, does what Serge wants to achieve --- see their statement on R, Brodgar and the GPL: www.brodgar.com http://www.brodgar.com/brodgar.htm#2.%20Brodgar%20and%20R Whilst, from a personal point of view agree with Michael's statement about producing an open source app and then sell support, we all don;t have to follow that moral.

Well, there's a big question as to whether non-GPL can link to GPL code. It's never been really tested in court. If I were you, I'd just make it open-source and sell your support for it. On Sun, May 11, 2008 at 5:19 AM, Serge Merzliakov <smerzlia at optusnet.com.au> wrote:
All, I am interested in devloping a commercial java-based (why the language is important is discussed later) GUI for R. The app would allow the GUI to edit R commands and the results displayed in varios means. I have investigated various java based libraries to invoke R and they follow the apache license model (friendlier to commercial software developers). I understand the that R is released under the GPL license, which I have a reasonable understanding of. SO my question is simple, Can I develop a a commerical GUI for R (which would require R to be isntalled separately on the machine) without having to also release my source code ? I am hoping that some of core R development team see this and can provide useful feedback. Regards, Serge
