[R] What is the Datasets License?

[Skipper Seabold]

Hello,

I saw that this question has been asked here before but couldn't find
an answer.  Are the raw datasets in R in the public domain?  Most are
based on quite old "classic" published results, so I would then assume
that the raw data is public domain rather than GPL.  Can anyone answer
this definitively, or is this maybe a question for R-devel?

Cheers,

Skipper
