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 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.

arXiv URL added to the package description and function documents.

Minor typo fix in the document.

A new function

`group_reduce()`

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.

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.

`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 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.

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.

- In
`L1centMDS()`

, setting`verbose=FALSE`

suppresses all the console messages. In the previous version, the final message was printed even when`verbose=FALSE`

.

- Initial CRAN submission.
