histNetwork function

Historical co-citation network

histNetwork creates a historical citation network from a bibliographic data frame.

histNetwork(M, min.citations, sep = ";", network = TRUE, verbose = TRUE)

Arguments

• M: is a bibliographic data frame obtained by the converting function convert2df. It is a data matrix with cases corresponding to manuscripts and variables to Field Tag in the original SCOPUS, OpenAlex, Lens.org and Clarivate Analytics Web of Science file.

• verbose: is logical. If TRUE, results are printed on screen.

NetMatrix		the historical co-citation network matrix
histData		the set of n most cited references
M		the bibliographic data frame
