wordcloud2

R interface to wordcloud for data visualization. Timdream's wordcloud2.js is used in this package.

Updates (May 17th, 2018)

Bugs below are fixed:

1. if you install wordcloud2 by install.packages("wordcloud2") (version 0.2.1), you will get the background image for either letterCloud() or the figPath option of wordcloud2.

2. if you install wordcloud2 by devtools::install_github("lchiffon/wordcloud2") (version 0.2.0), your plot on R-shiny will be unclickable.

Example of successfully deploying interactivate clickable wordcloud with special shape on R-shiny

devtools::install_github("JacobXPX/wordcloud2")
library(shiny)
library(wordcloud2)
library(tm)

shinyApp(
  ui = shinyUI(fluidPage(
    mainPanel(
      wordcloud2Output("wordcloud", clickedWordInputId = "selected_word")
    ),
    
    sidebarPanel(
      textOutput("selected_var")
    )
  )),
  server = shinyServer(function(input, output) {
    figPath = system.file("examples/t.png",package = "wordcloud2")
    wordcloud_plot <- wordcloud2(data = demoFreq, figPath = figPath, size = 0.6,color = "blue")
    output$wordcloud  <- renderWordcloud2(wordcloud_plot)
    output$selected_var <- renderText({ 
      paste("You have selected", input$selected_word)
    })
  })
)

run the above code and click refresh, it will work.
