The Virtual Observatory for the Study of Online Networks (VOSON) Lab in the School of Sociology at the ANU was formally established as part of a 2005 Australian Research Council Special Research Initiative (e-Research) grant. One of the activities of the VOSON Lab is the development of open-source tools that incorporate social science methods (in particular, Social Network Analysis) for collection and analysis of online behaviour. 

vosonSML (available on CRAN and GitHub) is an R package for the collection of social media data (Twitter, YouTube and Reddit) and the creation of various social networks for analysis.

VOSON Dashboard (available on CRAN and GitHub) is an interactive R shiny app that integrates social media data collection (via vosonSML),  network visualisation and analysis tools.
