numeric value or NA (default) to fill up outer set
(not part of union) of dimnames.
...
other argument, not used.
Details
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).
Value
An object similar to the input one.
