sigma

An R package with an interface to the sigma.js graph visualization library.

This package is intended as a simple demonstration of building R bindings to JavaScript libraries using the htmlwidgets framework.

Installation

You can install the sigma package from GitHub as follows:

devtools::install_github("jjallaire/sigma")

Usage

The sigma function takes a GEXF (Graph Exchange XML Format) file and produces an interactive visualization. For example:

library(sigma)
sigma(system.file("examples/ediaspora.gexf.xml", package = "sigma"))

You can also use the sigma function within R Markdown documents and even within Shiny applications. For example:

library(shiny)
library(sigma)

gexf <- system.file("examples/ediaspora.gexf.xml", package = "sigma")

ui = shinyUI(fluidPage(
  checkboxInput("drawEdges", "Draw Edges", value = TRUE),
  checkboxInput("drawNodes", "Draw Nodes", value = TRUE),
  sigmaOutput('sigma')
))

server = function(input, output) {
  output$sigma <- renderSigma(
    sigma(gexf, 
          drawEdges = input$drawEdges, 
          drawNodes = input$drawNodes)
  )
}

shinyApp(ui = ui, server = server)
