Tableau and R
The latest release of Tableau (8.1) has R integration. Tableau is free for academic use. Take a look at http://www.tableausoftware.com/about/blog/2013/10/tableau-81-and-r-25327?elq=5ddbf47b71804a108adabb1e91bd33fc. It could be a nice combination of the intuitive visual analytics of Tableau and the scripting capability of R.
