Details

The data comprises all games in the first German soccer league since its foundation in 1963. The data have been queried online from the official Web page of the DFB and prepared as a data frame in R by Daniel Dekic, Torsten Hothorn, and Achim Zeileis (replacing earlier versions of the data in the package containing only subsets of years).

Each year/season comprises 34 rounds (except 1963, 1964, 1991) so that all 18 teams play twice against each other (switching home court advantage). In 1963/64, there were only 16 teams, hence only 30 rounds. In 1991, after the German unification, there was one season with 20 teams and 38 rounds.
