WiFi Dashboard built using Shiny and the Mac airport utility
This Shiny app invokes system commands to run the airport utility on Mac OS X. If you're using some other operating system I can't help you.
For brevity the code expects that you've already created a symlink to the airport utility:
ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport /usr/local/bin/airport
