COPYRIGHT STATUS The bulk of this code is copyright by members of or all of the R Development Core Team. See the file COPYING for the exact conditions under which you may redistribute it. R as a whole is distributed under GPL version 2: most source files contain a copyright statement allow use of that file under GPL version 2 or later: the main exceptions are packages 'rpart' and 'survival' (GPL-2 only) and packages 'MASS', 'class', 'nnet' and 'spatial' (GPL-2 or GPL-3). The status of files used only in the Windows port is in file src/gnuwin32/COPYRIGHTS.win, which is appended to this file in binary Windows distributions. --------------------------------------------------- Some of the public header files are distributed under the more permissive terms of the file COPYING.LIB. This applies only to the files src/include/R.h src/include/Rdefines.h src/include/Rgraphics.h src/include/Rinternals.h src/include/Rmath.h src/include/S.h src/include/R_ext/*.h From the announcement of the change (2001-Feb-05) It came to our attention that some projects are interpreting GPL to mean that compiling against the header files or linking against a Windows import library brings the compiled code under the scope of GPL. This would mean it would be impossible to distribute binary versions of non-GPL packages with compiled code which called entry points in the R executable or DLL, of which there are many on CRAN. We encourage packages to be distributed under Open Source conditions, but accept that this is not possible for some contributions. Our intention is that export files and import libraries be `accessors' under clause 5 of the LGPL, so that in most cases no (additional) restrictions are imposed by compiling a package using the LGPL-ed components of R. To avoid any anomalies, the versions of the same files in R versions 1.0.0 to 1.2.1 may also be used under LGPL or GPL. As from R 2.3.0 import libraries are no longer used under Windows, and as from R 2.4.0 fewer export files are used under AIX. Some contributed files are also covered by the Library General Public License. These include (see also below) src/library/stats/R/embed.R src/library/stats/src/PPsum.c --------------------------------------------------- Some of the code contains different copyright statements.
