networkPlot: Plotting Bibliographic networks

Description

networkPlot plots a bibliographic network.

Usage

networkPlot(NetMatrix, n = 20, Title = "Plot", type = "kamada", vos.path = NULL, size = FALSE, noloops = TRUE, remove.multiple = TRUE)

Arguments

NetMatrix

is a network matrix obtained by the function biblioNetwork.

n

is an integer. It indicates the number of vertices to plot.

Title

is a character indicating the plot title.

type

is a character object. It indicates the network map layout:

type="circle"
Circle layout	type="sphere"
	Sphere layout
type="mds"
Multidimensional Scaling layout	type="fruchterman"
	Fruchterman-Reingold layout
type="kamada"
Kamada-Kawai layout	type="vosviewer"
	Network is plotted using VOSviewer software

vos.path

is a character indicating the full path whre VOSviewer.jar is located.

size

is logical. If TRUE the point size of each vertex is proportional to its degree.

noloops

is logical. If TRUE loops in the network are deleted.

remove.multiple

is logical. If TRUE multiple links are plotted using just one edge.

Value

It is a network object of the class igraph.

Details

The function networkPlot can plot a bibliographic network previously created by biblioNetwork. The network map can be plotted using internal R routines or using VOSviewer by Nees Jan van Eck and Ludo Waltman.

Examples

# EXAMPLE Co-citation network

data(scientometrics)

NetMatrix <- biblioNetwork(scientometrics, analysis = "co-citation", 
network = "references", sep = ";")

net <- networkPlot(NetMatrix, n = 20, type = "kamada", Title = "Co-Citation")
