rNVD3

Interactive Charts from R using NVD3

This R package helps users create interactive visualizations with NVD3, using a plotting interface similar to the lattice package.

Installation

You can install rNVD3 from github using the devtools package

require(devtools)
install_github('rNVD3', 'ramnathv')

Usage

rNVD3 uses a plotting interface similar to that of the lattice package. Here are a few examples you can try out in your R console.

Example 1: Discrete Bar Plot

require(rNVD3)
bar1 <- nvd3Plot(~gear, data = mtcars, type = "discreteBarChart", width = 600)
bar1$printChart("chart1")

Example 2: Stacked bar Plot

hair_eye = subset(as.data.frame(HairEyeColor), Sex == "Female")
p1 <- nvd3Plot(Freq ~ Hair | Eye, data = hair_eye, type = 'multiBarChart', width = 600)
p1$chart(color = c('brown', 'blue', '#594c26', 'green'))
p1$printChart('chart2')

rNVD3 is merely a wrapper around nvd3.js. More documentation and examples are underway.

Using with Shiny

rCharts is compatible with Shiny. Here is a link to the rCharts Shiny App.

## server.r
require(rNVD3)
shinyServer(function(input, output) {
  output$myChart <- renderChart({
    hair_eye = as.data.frame(HairEyeColor)
    p6 <- nvd3Plot(Freq ~ Hair | Eye, data = subset(hair_eye, Sex == input$gender), 
      type = input$type, id = 'myChart', width = 800)
    p6$chart(color = c('brown', 'blue', '#594c26', 'green'), stacked = input$stack)
    return(p6)
  })
})

## ui.R
require(rNVD3)
shinyUI(pageWithSidebar(
  headerPanel("rNVD3: Interactive Charts from R using NVD3.js"),

  sidebarPanel(
    selectInput(inputId = "gender",
      label = "Choose Gender",
      choices = c("Male", "Female"),
      selected = "Male"),
    selectInput(inputId = "type",
      label = "Choose Chart Type",
      choices = c("multiBarChart", "multiBarHorizontalChart"),
      selected = "multiBarChart"),
    checkboxInput(inputId = "stack",
      label = strong("Stack Bars?"),
      value = FALSE)
  ),
  mainPanel(
    showOutput("myChart")
  )
))

Credits

Most of the implementation in rNVD3 is inspired by rHighcharts and rVega. I have reused some code from these packages verbatim, and would like to acknowledge the efforts of its author Thomas Reinholdsson.
