plot_heterocitation_timeseries function

Function to plot the heterocitation share and heterocitation balance timeseries

This function plots and returns annual heterocitation share and heterocitation balance values.

plot_heterocitation_timeseries(gr_arg, labels, mini = -1, maxi = -1, cesure = -1)

Arguments

• gr_arg: Citation graph
• labels: Labels (i.e. names) of the two corpora featured in the graph.
• mini: Start year of the time window
• maxi: End year of the time window
• cesure: Year before which values should be cumulated. Default value is -1, which indicates that each year in the time window should be plotted.

Returns

Returns a dataframe with year and annual values for heterocitation share (sx1, sx2 and sxall for corpus A and B and global resp.) and heterocitation balance (dx1, dx2 and dxall for corpus A and B and global resp.).
