The Ontology Lookup Service

The Ontology Lookup Service (OLS), developed at the European Bioinformatics Institute (EBI), is a unified web interface to query multiple ontologies from a single location. The new version of the OLS uses a REST API.

The rols package uses functionality from the httr package to query the OLS directly from R.

See the package’s page on GitHub for details, documentation and vignette.

Installation

rols is available from the Bioconductor repository. The package and its dependencies can be installed

See also the rols Bioconductor page for on-line access to the vignette and the reference manual.
