| combine {arules} | R Documentation |
Provides the
S4 methods to
combine several objects based on
itemMatrix
into a single object.
Note, use union rather than c
to combine several mined
itemsets
(or rules) into a single set.
## 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 x to be combined. |
recursive |
"logical"; If recursive=TRUE,
the function recursively
descends through lists combining all their elements into a
vector. |
An object of the same class as x.

data("Adult")
### combine transactions
a1 <- Adult[1:10]
a2 <- Adult[101:110]
aComb <- c(a1, a2)
summary(aComb)
### combine rules
r1 <- apriori(Adult[1:1000])
r2 <- apriori(Adult[1001:2000])
rComb <- unique(c(r1, r2))
