    You can add a textarea using tags and it should be picked up by Shiny automatically:

    tags$textarea(id="foo", rows=3, cols=40, "Default value")

    Or if you’re more comfortable with straight HTML you can also do

    HTML('<textarea id="foo" rows="3" cols="40">Default value</textarea>')

    In either case, input$foo should reflect the textarea’s value.
