histPlot: Plotting historical co-citation network

Description

histPlot plots a historical co-citation network.

Usage

histPlot(histResults, n = 20, size.cex = TRUE, size = 5,
  labelsize = 0.8, arrowsize = 0.1, edgesize = 2, color = TRUE)

Arguments

histResults

is an object of class "list" containing the following components:

NetMatrix		the historical citation network matrix
Degree		the min degree of the network
histData		the set of n most cited references

is a network matrix obtained by the function histNetwork.

n

is integer. It defines the numebr of vertices to plot.

size.cex

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

size

is an integer. It define the point size of the vertices. Default value is 5.

labelsize

is an integer. It indicates the label size in the plot. Default is labelsize=1

arrowsize

is numerical. It indicates the edge arrow size.

edgesize

is numerical. It indicates the edge size.

color

is logical. If TRUE, egdes are colored according to citing references.

Value

It is a network object of the class igraph.

Details

The function histPlot can plot a historical co-citation network previously created by histNetwork.
