LIST: List Representation for Objects Based on ``itemMatrix''

Description

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

Usage

LIST(from, ...)
## S3 method for class 'itemMatrix':
LIST(from, decode = TRUE)
## S3 method for class 'transactions':
LIST(from, decode = TRUE)
## S3 method for class 'tidLists':
LIST(from, decode = TRUE)

Arguments

from

the object to be converted into a list.

...

further arguments.

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 dec

Value

• a list primitive.

Details

Using LIST with decode = TRUE is equivalent to the standard coercion as(x, "list"). 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).
