[Rd] authorship and citation

Simply advice:

The former co-author contributed, so he is still author and probably 
copyright holder and has to be listed among the authors, otherwise it 
would be a CRAN policy violation since even if he does not develop 
further on, he developed parts of the so far existing package (if you 
talk about a CRAN package).

I am not a lawyer, hence I cannot speak for copyright/license stuff in 
general, hence my comments only about CRAN policies.
