Re: [Rd] Non-GPL packages for R
Comrades, When talk turns to the purity of the revolution, and purge of packages then the guillotine can't be far behind. We all remember Lenin berating the "renegade Kautsky" for his "pragmatism," and we know where that led... So let me put in a good word for pragmatism, and incidentally for saving one of my own packages, SparseM, and perhaps eventually my neck. Last week Kurt asked me to look into a SparseM licensing quirk based on an inquiry from the Fedora folks. SparseM is GPL except for one routine cholesky.f written at Oakridge Lab by E. Ng and B. Peyton. Our version of the code was redistributed in the package PCx which was copywrited by the U. of Chicago, who specified that commercial users should contact someone at Argonne National Lab. Since the beginning we have retained this language in the License file of SparseM, even though the code in question was not actually developed as a part of PCx. I contacted one of the original PCx developers who responded as follows: The routine you mention was distributed with PCx but not part of it as you see from the legalese and not covered by the PCx copyright. I tried to interest the authors of that code in legal issues in around 1997 but could not get them motivated (frankly I also can't get too interested). To which I heartily concurred. If someone who is worried about getting sued would like to dig into this can of worms, then fine. But life is too short for the rest of us. This is quite a murky business, we shouldn't create incentives to make it murkier by covering up relevant language on licensing. But surely we can also all agree that CRAN has been a fantastic success, and adding new constraints on its operation is ill-advised.

GPL is more restrictive than most open source licenses so with the above you'd throw out a lot of "real" open source packages (namely those with more permissive open source licenses). The point was open distribution as Peter pointed out so GPL-compatible licenses would be one possibility (although it also disallows some open source licenses). Cheers, Simon 2) r-forge could be left "buyer beware" using DESCRIPTION information 3) We may want a specific repository for restricted packages (RANC?) How to proceed?

I doubt that there is consensus at the level you are suggesting (certainly I don't agree) and as Peter indicates below the issue is: what is maintainable with the resources we have, not what is the best solution given unlimited resources. Personally, I would like to see something that was a bit easier to deal with programmatically that indicated when a package was GPL (or Open source actually) compatible and when it is not. This could then be used to write a decent function to identify suspect packages so that users would know when they should be concerned. It is also the case that things are not so simple, as dependencies can make a package unusable even if it is itself GPL-compatible. This also makes the notion of some simple split into free and non-free (or what ever split you want) less trivial than is being suggested.

[Rd] Fortran routine affected by unrelated R code
Hi! When I run "R CMD check" on the current development version of my R package "frontier" [1], there is no difference between the output of the test scripts in the /tests/ folder and the saved output files (.Rout.save). However, if I change an R file in the /R/ folder, some calls to the Fortran code (called by ".Fortran()") return different results, although the change of the R file is not related to this, e.g. when I add the commands 'print("abc")' or 'newVariable <- 123' to an R file that even does not call the Fortran code. However, adding empty lines or comments does NOT change the values returned by the Fortran code. Different modifications of the R files lead to different results but the same modification always leads to the same results (hence, the results are perfectly reproducible). Since the Fortran code does a non-linear optimization, (slightly) different results (e.g. depending on starting values) could be expected. However, the values passed to the Fortran code are not affected by the modifications that alter the values returned by the Fortran code and I cannot sea any connection between the modification of the R files and the values returned by the Fortran code. Could this phenomenon be caused by an error in the Fortran code, by a bug in R, or is this a usual behavior that an expert would expect in this situation? Any hints are welcome!

[Rd] Logic ("!", "&", ...) on complex
The documentation, help("!") e.g., contains > Arguments: > x, y: logical vectors, or objects which can be coerced to such or > for which methods have been written. and then later > Numeric and complex vectors will be coerced to logical values, > with zero being false and all non-zero values being true. and that is consistent with what S-plus (3.4, 5.1, 8.0.2) gives. However, (nowadays at least) R internally checks and gives an error for complex arguments, even though as.logical(0 + 1i) works fine. > z <- complex(i=1) > !z Error in !z : invalid argument type > !as.logical(z) [1] FALSE I'm proposing to make R's behavior consistent with its documentation and predecessor.

Moreover, the (aptly named) field 'License:' in DESCRIPTION is now much more parseable and contains pertinent information. A number of more 'challenging' packages basically pass the buck on with an entry License: file LICENSE which refers to a file in the sources one needs to read to decide. This is e.g. at the basis of Charles' and my decision about what we think we cannot build via cran2deb [1]: non-free, non-distributable, non-commercial or otherwise nasty licenses. There are a couple of packages we exclude for this (or related reasons), and we have been meaning to summarise them with a simple html summary from the database table we use for cran2deb, but have not yet gotten around to it. Just like John and Ravi, I would actually be in favour of somewhat stricter enforcements. If someone decides not to take part in the gift economy that brought him or her R (and many other things, including at least 1880+ CRAN packages with sane licenses) then we may as well decide not to waste our time and resources on his project either and simply exclude it. So consider this as a qualified thumbs-up for John and Ravi's suggestion of a clearer line in the sand. Dirk [1] cran2deb is at http://debian.cran.r-project.org and provides 1800+ Debian 'testing' binaries for amd64 and i386 that are continuously updated as new packages appear on CRAN. With that 'apt-get install r-cran-foo' becomes a reality for almost every value of foo out of the set of CRAN packages. | | On Thu, Sep 10, 2009 at 1:50 PM, Prof. John C Nash wrote: |> Subject: Non-GPL packages for R |> |> Packages that are not licensed in a way that permits re-distribution on |> CRAN are frequently a source of comment and concern on R-help and other |> lists.
