d3Tree: Create a D3 tree or network display

In duncantl/RD3Device: R Graphics device to create D3 content

Description

These functions illustrate how we can create a display using D3's own display and layout classes. We do not use R's graphics engine for these displays, but use R to create the JavaScript code and pre-process the data.

This is just an illustration and could be done better (e.g. make the JavaScript use a function rather than a global variable and a script).

Usage

d3Tree(data, out = character(),
       htmlTemplate = system.file("template", "tree.html", package = "RD3Device"),
       jsTemplate = system.file("JavaScript", "tree.js", package = "RD3Device"),
       inline = length(out) < 2,
       d3 = "http://d3js.org/d3.v3.min.js", varName = "treeData")
d3Graph(data, out = character(),
        htmlTemplate = system.file("template", "graph.html", package = "RD3Device"),
        jsTemplate = system.file("JavaScript", "graph.js", package = "RD3Device"),
        inline = length(out) < 2,
        d3 = "http://d3js.org/d3.v3.min.js",
        varName = "graph")

Arguments

data	the data in R used to create the plot. This serialized to JavaScript form as JSON content.
out	a character vector giving the name of the file to which the completed HTML document will be written. If this has two elements, the second is used as the file name to which the JavaScript content will be written.
htmlTemplate	the name of a file containing the HTML content which we modify to create the actual HTML document in which to display the D3 plot
jsTemplate	the name of a JavaScript file containing code that
inline	a logical value which indicates whether to inline the data and code into the HTML document, or whether to write them as a separate JavaScript file and reference that.
d3	the URL or local file name for the D3 library
varName	the name of the JavaScript variable which is used to assign the data for the plot

Details

These mimic and adapt examples from the D3 gallery and blog posts

Value

If out is empty, the parsed HTML tree is returned. Otherwise, the name of the file to which the document was written is returned.
