If you’re looking to get Shiny Server running in EC2 without delay, just boot up an instance of our public Amazon Machine

This is part of a larger project I’m working on, but it’s useful enough to share (github version coming soon). The fine folks at @TeamCymru have a great service to map IP addresses to ASN/BGP information en masse. There are libraries for Python, Perl and other languages but none for R (that I could find).

This is the second of a two part reexamination of Florence Nightingale's data visualization based on her innovative cam diagrams (my term) shown in Figure 1. Figure 1.
