And there are certainly many existing R packages with
non-free/non-open licenses:

http://cran.r-project.org/web/packages/ff/LICENSE
http://cran.r-project.org/web/packages/minpack.lm/LICENSE
http://cran.r-project.org/web/packages/rngwell19937/LICENSE
http://cran.r-project.org/web/packages/SDDA/LICENSE
...
