LIST {arules}R Documentation

Creating a List Representation from Objects Based on “itemMatrix”

Description

Provides the generic function LIST and the S4 method to create a list representation from objects based on itemMatrix (e.g., transactions, tidList, or itemsets). These methods are also used for the coercion to list.

Usage

LIST(from, ...)
## S4 method for signature 'itemMatrix':
LIST(from, decode = TRUE)
## S4 method for signature 'transactions':
LIST(from, decode = TRUE)
## S4 method for signature 'tidList':
LIST(from, decode = TRUE)

Arguments

from the object to be converted into a list.
... further arguments are passed on.
decode a logical controlling whether the items/transactions are decoded from the column numbers internally used by itemMatrix to the names stored in the object from. The default behavior is to decode.

Details

LIST returns the object from as a list of vectors. Each vector represents one row of the itemMatrix (e.g., items in a transaction or itemset).

Value

a "list" primitive.
