File List

Here is a list of all documented files with brief descriptions:

array_ops.sql_in	Implementation of array operations in SQL
assoc_rules.sql_in	The assoc_rules function computes association rules for a given set of data. The data is assumed to have two dimensions; items (between which we are trying to discover associations), and a transaction id. This tranaction id groups the items by event and could also be a user id, date, etc. depending on the context of the data. This function assumes the data is stored in two columns with one transaction id and one item per row
