histPlot function

Plotting historical co-citation network

histPlot plots a historical co-citation network.

histPlot(
  histResults,
  n = 20,
  size = 5,
  labelsize = 5,
  remove.isolates = TRUE,
  title_as_label = FALSE,
  label = "short",
  verbose = 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
  M		the bibliographic data frame

  is a network matrix obtained by the function histNetwork.

• n: is integer. It defines the number of vertices to plot.

• size: is an integer. It defines 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=5.

• remove.isolates: is logical. If TRUE isolates vertices are not plotted.

• title_as_label: is a logical. DEPRECATED

• label: is a character. It indicates which label type to use as node id in the historiograph. It can be label=c("short", "title", "keywords", "keywordsplus"). Default is label = "short".

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

Returns

It is list containing: a network object of the class igraph and a plot object of the class ggraph.

Details

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

Examples

# EXAMPLE Citation network
## Not run:

data(management, package = "bibliometrixData")

histResults <- histNetwork(management, sep = ";")

net <- histPlot(histResults, n=20, labelsize = 5)
## End(Not run)
