swap_relations {OmnipathR} | R Documentation

## 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.

### Examples

    goslim_url <-
        "http://current.geneontology.org/ontology/subsets/goslim_generic.obo"
    path <- tempfile()
    httr::GET(goslim_url, httr::write_disk(path, overwrite = TRUE))
    obo <- obo_parser(path)
    unlink(path)
    rel_swapped <- swap_relations(obo$relations)
