Correct, the error is due the change of some codes:
- the dataset code
DB
was updated toDBS
(by the World Bank) - the addition of the new dimension named “frequency” (by me following our discussion)
- the changes of the country codes from 2 letters to 3 letters (by the World Bank)
I did not realize that this particular dataset was used as an example in the README!
I proposed a pull request to the author of the package, cf #12.
