function_get_graph_1_n_group_centrality_with_function: Creates a ggraph object.

In wordgraph: Graph Functionality of Free Associated Words

Description

Creates the ggraph object, i.e. the graph depicting the words containing the variables vector wordvars The combinations of all word pairs are computed for all concecutive pair of variables and the centrality of each word is calculated according to centralityfunction.

Usage

get.graph.1.n.group.centrality.with.function(
        wordvars,
        centralityfunction,
        data.df,
        iscircled = FALSE)

Arguments

wordvars	The vector containing the names of the variables
centralityfunction	The centrality function to apply. Acceptable entries one of: tidygraph::centrality_authority(), tidygraph::centrality_betweenness(), tidygraph::centrality_closeness(), tidygraph::centrality_pagerank(), tidygraph::centrality_eigen(), tidygraph::centrality_alpha()
data.df	The data frame where the variables belong.
iscircled	Should take also the combination between last and first variable (var_n - var1)? Default is FALSE.

Value

A list contains the graph data for the selected centrality index.

Examples

# It is a time consuming function...


agraph = get.graph.1.n.group.centrality.with.function(
    c("diet1stword", "diet2ndword", "diet3rdword"),
    tidygraph::centrality_authority(),
    freeassociationdata)

# To plot the graph simply call:
agraph

# The centrality scores are available at:agraph$data$centrality
hist(agraph$data$centrality)

# Other available centrality functions...

 agraph = get.graph.1.n.group.centrality.with.function(
             c("diet1stword", "diet2ndword", "diet3rdword"),
            tidygraph::centrality_betweenness(), freeassociationdata)

# Note: closeness centrality is not well-defined for disconnected graphs.
