dm_nest_tbl {dm}

Nest a table inside its dm

Description

dm_nest_tbl() converts a child table to a nested column in its parent table. The child table should not have children itself (i.e. it needs to be a terminal child table).

Usage

dm_nest_tbl(dm, child_table, into = NULL)

Arguments

dm

A dm.

child_table

A terminal table with one parent table.

into

The table to nest child_tables into, optional as it can be guessed from the foreign keys unambiguously but useful to be explicit.
