Combining Objects
Provides the S4 methods to combine several objects based on
itemMatrix
into a single object.
## S4 method for signature 'itemMatrix' c(x, ..., recursive = FALSE) ## S4 method for signature 'transactions' c(x, ..., recursive = FALSE) ## S4 method for signature 'rules' c(x, ..., recursive = FALSE) ## S4 method for signature 'itemsets' c(x, ..., recursive = FALSE)
x |
first object. |
... |
further objects of the same class as |
recursive |
a logical. If |
An object of the same class as x
.
