VOSONDash

CRAN_Status_Badge Downloads Total Github Release Dev Last Commit R build status

VOSONDash is an interactive R Shiny web application for the visualisation and analysis of social network data. The app has a dashboard layout with sections for visualising and manipulating network graphs, performing text analysis, displaying network metrics and the collection of network data using the vosonSML R package.

Installation

VOSONDash is an R package and must be installed before the app can be run.

Install the latest release on CRAN (v0.5.7):

install.packages("VOSONDash")

Install the latest release via GitHub (v0.5.7):

install.packages(
  pkgs = "https://github.com/vosonlab/VOSONDash/releases/download/v0.5.7/VOSONDash-0.5.7.tar.gz", 
  repo = NULL, type = "source")

Install the latest development version (v0.5.8.9000):

install.packages("remotes")
remotes::install_github("vosonlab/VOSONDash")

Once the VOSON Dashboard package is installed and loaded the Shiny web application can be run from the RStudio console using the runVOSONDash() function.

library(VOSONDash)
runVOSONDash()

Running the app for the first time

When run the VOSONDash app will check that all of the R packages that are required to make it work are installed. It is likely that some packages will be missing and the app will print a message indicating the missing packages and a command that can be used to install them.

For example:

> runVOSONDash()
=================================================
VOSONDash v0.5.8
...
Checking packages...

Error: Required packages missing.
- shinyjs
- visNetwork

Please install required packages before using VOSONDash:
install.packages(c("shinyjs", "visNetwork"))

The missing packages can be installed using the above install.packages command.

After installing required packages and running again the VOSONDash Shiny app will open up in the default web browser.

VOSON Dashboard

VOSONDash features an intuitive web interface with a section for 'Analysis' of graph data loaded from igraph objects and a section for the 'Collection' of social media data using vosonSML.

Analysis

Network and text analysis of graph data.

  • Network Graphs: Visualise and modify networks
  • Network Metrics: Calculate node and network level metrics
  • Text Analysis: Word frequency, word clouds and sentiment
  • Assortativity: Calculate homogeneity and homophily indexes (if VOSON categorical node attributes present)

Collection and Network Creation

Graphical interfaces for collecting network data from social media API's.

  • Collect: Twitter, youtube and reddit network data
  • Create: different types of networks from the data such as activity, actor, twomode and semantic networks

Special thanks

This application would not be possible without key packages by other authors in the R community, particularly the shiny, shinydashboard, DT and shinyjs packages. Graph visualisations created with igraph and visNetwork, and text analysis with support from tm, SnowballC, wordcloud and syuzhet packages.
