LIST {arules} | R Documentation |
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 list
.
LIST(from, ...) ## S4 method for signature 'itemMatrix': LIST(from, decode = TRUE) ## S4 method for signature 'transactions': LIST(from, decode = TRUE) ## S4 method for signature 'tidLists': LIST(from, decode = TRUE)
from |
the object to be converted into a list. |
... |
further arguments. |
decode |
"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.
|
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).
a "list"
primitive.
