	  That's definitely consistent with the GPL-2 license it carries as 
long as you aren't trying to charge royalties for use of your package. 
See:


https://CRAN.R-project.org/package=gdata


	  And the tarball is available at this link to make it easy for you to 
do that.


	  Regarding my earlier comment about to gdata being potentially 
obsoleted, I don't see evidence of that now:  There is only one "Note" 
in the "CRAN checks", and that would seem to be a problem more with that 
platform than with the gdata package.  The problem that Brian Ripley 
mentioned in his email about this 2020-09-11 may have been with 
something else that gdata used that has since been fixed.


	  I would normally prefer to let the gdata maintainers continue to 
maintain a function like this.  However, you seem to have a compelling 
reason for copying that function and only citing the original for the 
source of where you got the code.  You might include, e.g., 
\code{\link[gdata]{rename.vars}}.


	  CAVEAT:  Please ignore the above if contradicted by someone more 
knowledgeable than I am about CRAN and R policies and recommendations.
