Dear XYZ
You can use the R package rdb to access the data from the database, which we're in the middle of rebranding to Referendum Database (RDB).
We wrote a short introduction which should help get you started. The corresponding codebook is found here.
Please report any issues you may encounter with the R package on GitLab.
I hope I could help.
Best regards, Salim
