A collection of functions to extract citation information from 'R' packages and to deal with files in 'citation file format' (<https://citation-file-format.github.io/>), extending the functionality already provided by the citation() function in the 'utils' package.

In searching for research articles, we often want to
obtain lists of references from across studies, and also obtain lists
of articles that cite a particular study. In systematic reviews, this
supplementary search technique is known as 'citation chasing': forward
citation chasing looks for all records citing one or more articles of
known relevance; backward citation chasing looks for all records
referenced in one or more articles. Traditionally, this process would
be done manually, and the resulting records would need to be checked
one-by-one against included studies in a review to identify potentially
relevant records that should be included in a review. This package
contains functions to automate this process by making use of the
Lens.org API. An input article list can be used to return a list of
all referenced records, and/or all citing records in the Lens.org
database (consisting of PubMed, PubMed Central, CrossRef, Microsoft
Academic Graph and CORE; <https://www.lens.org>).
