Combine R objects by rows and columns.

1 2 |

`x, y` |
objects to combine, see Details. |

`fill` |
numeric value or |

`...` |
other argument, not used. |

`x`

and `y`

are combined in a left join manner,
meaning that all the elements in
`x`

are retained, and only non-overlapping elements in `y`

are used.
Elements of the returning object that are not part of `x`

and `y`

(outer set) are filled up with `fill`

.

If relational table in `x`

is `NULL`

,
corresponding values from same table
of `y`

are used.

`mbind2`

combines `x`

and `y`

so that inner set is
calculated as sum of corresponding elements from `x`

and `y`

(unlike in `mbind`

with a left join manner).

An object similar to the input one.
