L1centrality 0.3.1

• print.L1centNB() can now handle a graph with a missing vertex name (i.e., V(g)$name == NULL). If vertex names are missing, the function automatically sets them to V1, V2, ..., and prints them.

• The type argument is set to 1 in the quantile() function inside the L1centLOC() and L1centEDGE() functions.

L1centrality 0.3.0

Major updates

• A new function Gini() computes the Gini coefficient. (See the document named Heterogeneity.)

• L1cent() now returns an object of class L1cent. summary() and print() methods are implemented for this new class.

• L1centGROUP() now returns an object of class L1centGROUP. print() method is implemented for this new class.

• L1centLOC() now returns an object of class L1centLOC. summary() and print() methods are implemented for this new class.

• L1centNB() now returns an object of class L1centNB. summary() and print() methods are implemented for this new class.

• L1centEDGE() now returns an object of class L1centEDGE. summary() and print() methods are implemented for this new class.

• Implementation of L1centEDGE() corrected.

• print() methods is implemented for the L1centMDS class. The L1centMDS() function formerly returned a length four list with label of the vertices as one component. This component is now an attribute of the returned list, i.e., the L1centMDS() now returns a length three list. (See the document for L1centMDS().) As a result, the plot() method for the L1centMDS is modified as well.

Minor updates

• Minor typo fix in the document.

• New document 'Heterogeneity' added. It includes the Lorenz_plot() function and the Gini() function.

• New document 'Summary' added. It includes all summary() method in this package.

L1centrality 0.2.1

• arXiv URL added to the package description and function documents.

• Minor typo fix in the document.

L1centrality 0.2.0

Major updates

• A new function reduce_graph() constructs the group reduced graph, which is used in computing the group L1 centrality and group L1 prestige.

• A new function L1centGROUP() computes the group L1 centrality and group L1 prestige. It supports undirected and directed graphs, as well as vertex and edge weighted graphs.

Minor updates

• Error message of validate_matrix() (an internal function for validating the given graph) corrected.

• DESCRIPTION and the documentation L1centrality-package updated to include information on the group L1 centrality/prestige.

• Minor typo fix in the document.

L1centrality 0.1.1

Major updates

• L1cent(), L1centNB(), L1centLOC() now support (strongly connected) directed graphs. Use the new parameter mode to measures the prominence of each vertex in terms of making a choice (mode = "centrality") or receiving a choice (mode = "prestige"). If the graph is undirected, mode does not affect the outcome.

Minor updates

• Minor typo fix in the document.

• \() changed to function() for compatibility (L1centNB.matrix()).

• Fixed error in the L1centLOC() function.

• Added package overview table to the L1centrality-package document.

• arXiv URL added to the package description and function documents.

L1centrality 0.0.3

• Minor typo fix in the document.

• L1centLOC() and L1centEDGE() made more efficient.

• \() changed to function() for compatibility (L1centMDS.matrix()).

• The vertex multiplicity parameter eta generalized to nonnegative values (L1cent(), L1centEDGE(), L1centLOC(), L1centNB()). It previously accepted only positive values.

L1centrality 0.0.2

• Initial CRAN submission.
