get the ontology based on a short tag and year

getOnto(ontoname = "cellOnto", year_added = "2023")

Arguments

ontoname: character(1) must be an element in `valid_ontonames()`
year_added: character(1) refers to `rdatadateadded` in AnnotationHub metadata

Note

This queries AnnotationHub for "ontoProcData" and then filters to find the AnnotationHub accession number and retrieves the ontologyIndex serialization of the associated OBO representation of the ontology.

Examples

co = getOnto()

tail(co$name[1000:1500])
