An R-Tool for Comprehensive Science Mapping Analysis
Tool for quantitative research in scientometrics and bibliometrics.
It provides various routines for importing bibliographic data from SCOPUS (< http://scopus.com>),
Clarivate Analytics Web of Science (< http://www.webofknowledge.com/>), Cochrane Library (< http://www.cochranelibrary.com/>)
and PubMed (< https://www.ncbi.nlm.nih.gov/pubmed/>) databases, performing bibliometric analysis
and building networks for co-citation, coupling, scientific collaboration and co-word analysis.
