•
•
Communities
Business
Human diseases
Animal species (who eats whom relationship)
• Consists of two parts
• Actors (nodes): Circles in the network
• Social relationship (tie): Lines that connects
nodes
What is Network analysis?
• What we can do with the analysis is to
• Visualize networks
• Describe specific characteristics of overall network structure
• Build mathematical and statistical models
• It has been developed a lot in the last 30 years because of
• A number of influential theories of network structure and formation
• Advances in computational power and speed
• Advances in statistical network theory
5 Reasons why R is suitable for network analysis
• Wide Scope
• Comprise thousands of packages and functions that allow to manage,
analyze and visualize various data
• Free and open nature
• No need to pay to use
• R code and packages are continuously being enhanced by R user
community
• Data and Project Management Capabilities
• Powerful data management, cleaning, import and export capabilities
• User can manage any type of complex network project
• Integrated Development Environment called Rstudio makes easy to use R
5 Reasons - continued
• Breadth of Network packages
• There are dozens of network-related packages. For example,
•
•
•
•
network and igraph : Manage and store R network data
Intergraph : Exchange data between formats
Sna : Analyze and visualize data
Ergm : Build sophisticated network modeling
• Strength of Network Modeling
• Provide comprehensive and dynamic network modeling
Things required to use resources in the book
• First, need to download and install UserNetR package
• Then, load the package
• In order to look at the documentation of the package
