Combines two object of class `"RecLinkData"`

or `"RecLinkResult"`

by concatenating comparison patterns
and, if available, weights and classification results.

`x, y` |
The objects to combine. |

An object with class corresponding to the input objects which represents
the concatenation of `x`

and `y`

. Its
component `pairs`

is `rbind(x$pairs, y$pairs)`

. If both `x`

and `y`

have weights stored in component `Wdata`

, the result
gets `c(x$Wdata, y$Wdata)`

as component `Wdata`

. For the
`"RecLinkResult"`

method, the result also includes the
concatenation of the predicted classes in `x`

and `y`

as
component `prediction`

.

The methods perform only a minimum of integrity checks, so the user has to make sure that the underlying data, the formats of comparison patterns (e.g. excluded columns) and the type of weights (method and parameters of weight calculation) match.
