## Combining Objects

### Description

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.

### Usage

    ## 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)

### Arguments

`x` | first object.
`...` | further objects of the same class as `x` to be combined.
`recursive` | a logical. If `recursive=TRUE`, the function recursively descends through lists combining all their elements into a vector.

### Value

An object of the same class as `x`.

### Examples

    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))
    rComb
