An R Client for the Europe PubMed Central RESTful Web Service
(see <https://europepmc.org/RestfulWebService> for more information). It
gives access to both metadata on life science literature and open access
full texts. Europe PMC indexes all PubMed content and other literature
sources including Agricola, a bibliographic database of citations to the
agricultural literature, or Biological Patents. In addition to bibliographic
metadata, the client allows users to fetch citations and reference lists.
Links between life-science literature and other EBI databases, including
ENA, PDB or ChEMBL are also accessible. No registration or API key is
required. See the vignettes for usage examples.
