If you are not distributing the package to anyone else, you can ignore 
the warning about the bad license field.

If you plan to distribute it on a public repository, you should ask the 
policies of the repository to find out what to do about this. CRAN 
policies are listed at 
http://cran.r-project.org/web/packages/policies.html.  There's a link 
from there to the list of acceptable licenses, and it includes some CC 
licenses.

If some parts of the package are licensed one way and others are 
licensed in another way, you'll probably need a COPYRIGHTS file to 
describe it.

Other repositories (e.g. Bioconductor, Github) presumably have their own 
policies on this, but I don't know where to find those.
