Indicate that R package is proprietary

Question

Is there a standard way how to indicate that R package is proprietary, owned by a company and should not be shared outside of the company? Right now, I am using this in DESCRIPTION file:

License: Proprietary, ownership of XX Company

Answer 1

You can use the License: field of the DESCRIPTION file and the LICENSE file for the actual license. For more info see: http://cran.r-project.org/doc/manuals/r-release/R-exts.html#Licensing
