title: R shiny: Add weblink to actionButton
body: <p>I have a box in my shiny application that has a button included within a shiny dashboard box like this:</p>
  
  <pre><code>shiny::fluidRow(
    shinydashboard::box(title = "Intro Page", "Some description...", 
        shiny::actionButton(inputId='ab1', label="Learn More", icon = icon("th"))
    )
  )
  </code></pre>
  
  <p>I want to include a weblink in the button such that when I click on it, it should open the corresponding webpage in a new tab. </p>
  
  <p>I know that I can do this instead:</p>
  
  <pre><code># this does not create a submit button though, it just creates a link.
  tags$div(class = "submit",
           tags$a(href = "www.google.com", 
                  "Learn More", 
                  target="_blank")
  )
  </code></pre>
  
  <p>But with actionButton, there is a nice button and I can add an icon to it which looks aesthetically better. </p>
