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.

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
Wndows distributions.

    ---------------------------------------------------

The 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 export files are no longer used under AIX.
