Reference Publication Year Spectroscopy

Description

rpys computes a Reference Publication Year Spectroscopy for detecting the Historical Roots of Research Fields. The method was introduced by Marx et al., 2014.

Usage

rpys(M, sep = ";", timespan = NULL, graph = T)

Arguments

M

is a data frame obtained by the converting function convert2df. It is a data matrix with cases corresponding to articles and variables to Field Tag in the original ISI or SCOPUS file.

sep

is the cited-references separator character. This character separates cited-references in the CR column of the data frame. The default is sep = ";".

timespan

is a numeric vector c(min year,max year). The default value is NULL (the entire timespan is considered).

graph

is a logical. If TRUE the function plot the spectroscopy otherwise the plot is created but not drawn down.

Value

a list containing the spectroscopy (class ggplot2) and three dataframes with the number of citations per year, the list of the cited references for each year, and the reference list with citations recorded year by year, respectively.
