Sorry if this an inappropriate place to post this question - I have read
the FAQ's and looked through the mailing list archives but couldn't find
an answer to my problem. I am working my way through the GPL to try and
answer this myself, but I was wondering if someone could offer some
guidance.
I am working on a commercial software development project for which data
analysis is to be integrated into the program. If we were to distribute
copies of our software, what would be the effect if the R interpreter
(necessary to run scripts that are written by me to do data analysis)
were also part of the software? In particular how would that effect the
open/closed nature of the source code for the rest of the project? Since
the results of the data analysis (the "output" of the program) is what
is of interest, does this mean that the rest of the software for the
project must be distributed according to the GPL? Does the use of
scripts to be run by the R interpreter constitute altering the program
(I am guessing not)? What if I made calls to R from a C program? (Note
that I don't plan to redistribute altered versions of the R interpreter).
I will be judicious in the modules I use so as not to use those that are
expressly for non-commercial use, but for those covered under the GPL
(and R itself) I am a bit unclear as to the consequences of distributing
our software with the R interpreter (should we decide to do so).
Thanks,
Chris
