Screencast version of workshop originally delivered at IASSIST (iassistdata.org) Annual Conference, June 2015.  

Part 10a introduces the Tessera project to provide simplified MapReduce-type functions and data visualization in the R statistical software environment, along with instructions on spinning up an Amazon EC2 instance to run Tessera.  While the cluster installs, issues present in big data analysis such as high-dimensional data and sparse data are discussed.
