Quick and Simple D3 Network Graphs from R

Sometimes I just want to quickly make a simple D3 JavaScript directed network graph with data in R. Because D3 network graphs can be manipulated in the browser–i.e. nodes can be moved around and highlighted–they're really nice for data exploration. They're also really nice in HTML presentations. So I put together a bare-bones simple function–called d3SimpleNetwork for turning an R data frame into a D3 network graph. ArgumentsBy bare-bones I mean other than the arguments indicating the Data data frame, as well as the Source and Target variables it only has three arguments: height, width, and file. The data frame you use should have two columns that contain the source and target variables. Here's an example using fake data:Source <- c("A", "A", "A", "A", "B", "B", "C", "C", "D") Target <- c("B", "C", "D", "J", "E", "F", &…
