R help - Aug 2004 - License for including datasets in packages

Dear All,

I would like to publish a function for 'heckit' estimations together
with two
examples from Greene's and Wooldridge's econometric textbooks. 
These examples use the dataset of Mroz (1987) that is also available in John 
Fox' "car" package. However, not all variables that are used in my
examples
are available in the "car" package. Therefore, I want to put the full
Mroz
dataset in my package. This full dataset can be downloaded from some internet 
sites (e.g. pages.stern.nyu.edu/~wgreene/Text/econometricanalysis.htm, 
www.stata.com/texts/eacsap/), but I did not find any license information. 

Whom do I have to ask wether I am allowed to put these data in a GPLed R 
package? (Mr. Mroz, Mr. Greene, STATA, University of Michigan (PSID), . . . )

@John: Do you have any license information on these data?

Thanks,
Arne

Dear Arne,

I'm not a lawyer, but I believe that data per se are not copyrightable.

Regards,
 John
