L1centrality 0.4.0

Major updates

• summary() methods now return an object of class table.

• A new argument weight_trasform is added to L1cent(), L1centGROUP(), L1centNB(), L1centLOC(), L1centMDS(), and group_reduce() generic functions. This is an optional function to transform the edge weights.

• plot() methods added and enhanced:

  • plot.L1centMDS(): Vertex color and vertex label attributes in an igraph object are automatically passed to this plot method.

  • plot.L1cent(): When there is no second argument (y), it draws a Lorenz curve. Otherwise, it draws a scatter plot. Axes labels are automatically added.

  • plot.L1centLOC(): When the graph is evaluated at a single locality level (alpha), it draws a Lorenz curve or a scatter plot. Otherwise, it draws a line plot of local L1 centrality change of each vertex at a uniform margin.

  • plot.L1centEDGE(): Draws a directed graph where each vertex gives an edge to its local median. Colors and labels of the vertices are automatically set from the given igraph object.

Minor updates

• Added citations of three relevant papers to the documentations, DESCRIPTION, and README files.

• Generated a CITATION file for citing this package.

• Removed 'Summary' documentation and incorporated the documentation for each summary() method into the corresponding function help pages.

• Minor fix in the print() and summary() methods.

• Examples modified.
