Metrics: Metrics

In RImpact: Calculates Measures of Scholarly Impact

Description

Measures scholarly impact using modern citation-based indices.

Usage

Metrics(citation.counts, publishing.age = 0, display = TRUE)

Arguments

citation.counts	Number of times each aritcle has been cited. (vector)
publishing.age	Age of the first article author has published. (scalar)
display	Whether to display metrics (if TRUE, the default) or direct output to a file (if FALSE).

Value

h.index	h index, the largest number h such that at least h articles are cited h times each (Hirsch, 2005).
tapered.h.index	Tapered h index, credit decreases for citations farther from the origin (Anderson, Hankin, & Killworth, 2008).
f.index	f index, largest value f such that the harmonic mean fo rthe f most highly cited articles is at least f (Tol, 2009).
g.index	g index, larfest value g such that th emean citations for the g most highly cited articles is at least g (Egghe, 2006).
hg.index	hg index, geometric mean of h and g (Alonso, Cabrerizo, Herrera-Viedma, & Herrera, 2010).
a.index	a index, mean citations for the papers in Hirsch core (Jin, 2006).
m.index	m index, median citations for papers in Hirsch core (Bornmann, Mutz, Daniel, 2008).
r.index	r index, square root of citations for papers in Hirsch core (Jin, Liang, Rousseau, Egghe, 2007).
weighted.h.index	h index weighted by citation impact (Egghe & Rousseau, 2008).
q2.index	q2 index, geometric mean of h and m indexes (Cabrerizo, Alonso, Herrera-Videma, & Herrera, 2010).
e.index	e index, excess citations for papers in Hirsch core (Zhang, 2009).
max.product	Maximum product index, maximum product of article's rank and citation count (Kosmulski, 2007).
sqrt.max.product	Rescales maximum product index from an area to a distance measure.
h2.index	h2 index, analogous to h index with more stringent criterion (Kosmulski, 2006).
m.quotient	m quotient, controlling h index for publishing age (Hirsch, 2005).
tapered.m.quoteient	Controlling tapered h index for publishing age.
