np_rows: Make h_table no-parent rows

In sakrejda/hierarchy: Package for handling inputs to hierarchical models.

Description

The no-parent rows are the parents of all regions that themselves have no parent regions. These are identified as the rows who's parent_region_id does not appear in the 'id' column. They are added so that all parts of the hierarchy terminate at a well-defined "parent_region_level" regardless of the depth of the hierarchy.

Usage

np_rows(table)

Arguments

table

h_table to check for no-parent codes.

Value

data frame rows for all no-parent rows (with ZERO as parent).
