27.13.4 Union of PGX Frames
You can join two PgxFrame
s that have compatible columns (that is,
same type and order).
opg4j> <first-frame>.union(<secondframe>).print()
<first-frame>.union(<first-frame>).print();
<first-frame>.union(<first-frame>).print()
The rows of the resulting
PgxFrame
are the union of the rows from the two original frames.
