europepmc facilitates access to the Europe PMC RESTful Web Service.
Europe PMC covers life science literature and gives access to open access full texts. Europe PMC ingests all PubMed content and extends its index with other sources, including Agricola, a bibliographic database of citations to the agricultural literature, or Biological Patents.
For more infos on Europe PMC, see:
Levchenko, M., Gou, Y., Graef, F., Hamelers, A., Huang, Z., Ide-Smith, M., ? McEntyre, J. (2017). Europe PMC in 2017. Nucleic Acids Research, 46(D1), D1254?D1260. https://doi.org/10.1093/nar/gkx1005

By default, epmc_search() returns 100 records. To adjust the limit, simply use
the limit parameter.

epmc_hits_trend()There is also a nice function allowing you to easily create review graphs like described in Maëlle Salmon's blog post:
a <- europepmc::epmc_hits_trend("Malaria", period = 1995:2016, synonym = FALSE)
