This dataset is generated by the method described by Agrawal and Srikant (1994) using the reimplementation in arules which also retains the patterns used in the generation process.
The format is:
Agrawal.db contains the dataset (1000 items/20000 transactions)
Agrawal.pat contains the
patterns that were used to create the dataset.
