Making Static & Interactive Maps With ggvis (+ using ggvis maps w/shiny)

Even though it’s still at version 0.4, the ggvis package has quite a bit of functionality and is highly useful for exploratory data analysis (EDA).

A short post: A Shiny Application for Visualizing Colors in R

Turn R (Shiny) Scripts Into Double-clickable OS X Applications With One Line of Code

Now, I know it’s not hard to enter: shiny::runGist('95ec24c1b0cb433a76a5', launch.browser=TRUE) at an R console, but I’ll wager...
