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).
