Include a javascript file in Shiny app

Question

I need to include a js library into my Shiny app. Currently I use includeHTML to include the script directly into html codes. e.g.

includeHTML(\'URL.js\')
<         


        

Answer 1

 └──shiny
    ├── server.R
    ├── ui.R
    └── www
        ├── stylesheet.css
        └── js
             └── hoge.js

ui.R

Either one of them will work

1. tags$head(HTML(""))

2. HTML('
              
              
          ')
