Reverse the direction of ontology relations

Description

Reverse the direction of ontology relations

Usage

swap_relations(relations)

Arguments

relations

The 'relations' component of the data returned by obo_parser or any '...ontology_download' function such as go_ontology_download. Depending on the tables argument of those functions the 'relations' can be a data frame or a nested list.

Value

Same type as the input, but the relations swapped: if in the input these pointed from each child to the parents, in the output they point from each parent to their children, and vice versa.

obo <- obo_parser(path)
