Network Analysis in Risk Reports

Introduction

The network analysis function creates a related items web that can be beneficial for capturing related risk items. This figure is created by combining an items data frame with a relations dataframe. These items are then passed into an igraph object which is then rendered into the dendrogram html widget.

Gather Risk Data 

db_risk <- rarr::db_risk
db_action <- rarr::db_action
db_decision <- rarr::db_decision

Wrangle Risk Data 

risk <- rarr::wrangle_risk(db_risk)
action <- rarr::wrangle_action(db_action)
decision <- rarr::wrangle_decision(db_decision)
db_rel_action_action <- rarr::db_rel_action_action
db_rel_dec_dec<- rarr::db_rel_dec_dec
db_rel_dec_action<- rarr::db_rel_dec_action
db_rel_risk_action <- rarr::db_rel_risk_action
db_rel_risk_dec <- rarr::db_rel_risk_dec
db_rel_risk_risk <- rarr::db_rel_risk_risk
rel_action_action <- rarr::wrangle_rel_action_action(db_rel_action_action)
rel_dec_dec <- rarr::wrangle_rel_dec_dec(db_rel_dec_dec)
rel_dec_action <-rarr::wrangle_rel_dec_action(db_rel_dec_action) 
rel_risk_action <-rarr::wrangle_rel_risk_action(db_rel_risk_action)
rel_risk_dec<- rarr::wrangle_rel_risk_dec(db_rel_risk_dec)
rel_risk_risk <-rarr::wrangle_rel_risk_risk(db_rel_risk_risk)

Create a dataframe of wrangled risks, actions, and decisions 

items <- rarr::create_items(risk, action, decision)

Build a dataframe of all wrangled relationships 

relations<-rarr::create_relations(rel_action_action, rel_dec_action, rel_dec_dec,
                                  rel_risk_action,rel_risk_dec,rel_risk_risk)

Create igraph object to pass into dendrogram 

relate_igraph <- igraph::graph_from_data_frame(d = relations, 
                                               vertices = items, 
                                               directed = FALSE)
edgebundleR::edgebundle(relate_igraph, 
                        tension = 0.8, 
                        fontsize = 13,
                        padding = 70)
