ancestry_graph: Build a connected ancestry graph.

In lbartnik/repository: Object Repository for R

Description

For each identifier in ids, ancestry_graph creates and returns a list with the two following keys:

Usage

ancestry_graph(chosen_ids, all_ids, store)

Arguments

chosen_ids	identifiers, possibly disconnected
all_ids	all identifiers, superset of chosen_ids
store	object store; see storage::object_store

Details

• parents which is read directly from store

  • children which is inferred from parents

Those lists are wrapped in a single list and named with values from ids. Furthermore, ancestry_graph verifies that all values present in parents and children are also present in ids and that the resulting graph is connected, that is, whether there is a path between any pair of nodes.

Value

A list named according to ids; each element is a list with two keys: parents and children.
