DEPRECATED
This package is no longer necessary, as the GPDD can now be downloaded directly as .csv files from the KNB repostitory: https://doi.org/10.5063/F1BZ63Z8
This package originally provided an R interface the Global Population Dynamics Database, where data was served from a no-longer-maintained API and provided only in the Microsoft Access DataBase format, both of which made access more difficult for R users.
