[R] R licence

[Matthew Dowle]

Duncan,

Letting you know then that I just don't see how the first paragraph here :

http://www.revolutionanalytics.com/downloads/gpl-sources.php

is compatible with clause 2(b) here :

http://www.gnu.org/licenses/gpl-2.0.html

Perhaps somebody could explain why it is?

Matthew
