Hi Roger, I hope you remember the discussion we had two years ago when I tried to package spdep for Debian as a dependency to test some R epipdemiology tools. I somehow gave up since the packages can be run with out spdep. However, we have now some bioinformatics tools that have a strong dependency and so we need to dive into this again.
As you can read below the Debian ftpmaster has reviewed the source code of spdep and found a weak part in the licensing. If you ask me this issue is also relevant for distributing spdep code on CRAN but nobody has stumbled upon this before. It would be great if you could clarify the license of these pieces of code or replace it by some alternative free code. Kind regards and thanks for your support Andreas.
