EMBI data availability

Correct, the error is due the change of some codes:

  • the dataset code DB was updated to DBS (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.
