I'm doing a review of a paper (very well written, I think) for a journal with a fairly good reputation.
This is my first review, and I have a question regarding data availability which is, according to the journal policy, a necessary condition to publish:
The data, code or other digital research materials must be publicly accessible and clearly indicated as such.
The problem is that the dataset used in the analysis can only be retrieved under the payment of a fee from a link provided by the authors.
How should I behave in this case?
The journal asked me if data was accessible and if it was adequate to allow replication. The honest answer is "no", but the authors could not have done otherwise, since the data has a license and is not free to share.
