`x,y, el, set` |
sets of associations or itemMatrix objects. |

All S4 methods for set operations are defined for the
class name `"ANY"`

in the signature,
so they should work for all S4 classes for which the following
methods are available: `match`

, `length`

and `unique`

.

`union`

, `intersect`

, `setequal`

and `setdiff`

return an
object of the same class as `x`

and `y`

.

`is.element`

returns a logic vector of length `el`

indicating
for each element if it is included in `set`

.
