### Original description

#### Installation

```

devtools::install_github("lchiffon/wordcloud2")

```

knitr and shiny is support in wordcloud2 package.

#### Example

```

library(wordcloud2)

wordcloud2(demoFreq, size = 1,shape = 'star')

```

![1](examples/img/1.png)

```

wordcloud2(demoFreq, size = 2, minRotation = -pi/2, maxRotation = -pi/2)

```

![1](examples/img/2.png)

```

wordcloud2(demoFreq, size = 2, minRotation = -pi/6, maxRotation = -pi/6,

  rotateRatio = 1)

```

#### Chinese version

```

## Sys.setlocale("LC_CTYPE","eng")

wordcloud2(demoFreqC, size = 2, fontFamily = "微软雅黑",

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

Thanks [JacobXPX](https://github.com/JacobXPX)'s contribution to this feature:

Thanks [AdamSpannbauer](https://github.com/AdamSpannbauer) for pointing out the [issues](https://github.com/Lchiffon/wordcloud2/issues/45).

Additional features are added or modified:

1. hover information display are fixed, refering [AdeelK93](https://github.com/AdeelK93)'s previous work, thanks!

2. multiple wordclouds which seperatedly click are supported.

3. `clickedWordInputId` is changed to be automatically generated by: paste0(outputId, "_clicked_word")).

See sample below for more details:

```

library(shiny)

library(wordcloud2)

shinyApp(

  ui=shinyUI(fluidPage(

    #using default clicked word input id

    wordcloud2Output("my_wc", width = "50%", height = "400px"),

    #using custom clicked word input id

    wordcloud2Output("my_wc2", width = "50%", height = "400px"),

    

    verbatimTextOutput("print"),

    verbatimTextOutput("print2")

  )),

  server=shinyServer(function(input,output,session){

    

    figPath = system.file("examples/a.png",package = "wordcloud2")

    

    output$my_wc  = renderWordcloud2(wordcloud2(data = demoFreq, figPath = figPath, size = 0.4,color = "blue"))

    output$my_wc2 = renderWordcloud2(wordcloud2(demoFreq))

    

    #using default clicked word input id

    output$print  = renderPrint(input$my_wc_clicked_word)

    #using custom clicked word input id

    output$print2 = renderPrint(input$my_wc2_clicked_word)

  })

)

```

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